Huzzah!

I too am a fan of SL.

No one ever said a 'gimmick' won't work for anyone. SL was tried years ago. Poor Bryson Dechambeau came along and pre-maturely got Cobra to give it a go. Unfortunately BD has so far been a bust. Pretty much a flop when you consider the company he shares being  NCAA/US Amateur champ with. It's great that you play well with SL. Some people hit their best drives ever with the Hammer. However, statistics don't lie and the fact is nothing revolutionary came about with SL and nothing will. Sorry. {insert classic comic stamp} GIMMICK.

Single Length clubs are not intended for professional golfers like Vinsk -- so if you're a 9 handicap or better like he is, don't even try single length clubs because you don't need them.

Actually, I believe that single length clubs are a disadvantage for professional golfers since the descent angle is more shallow on the longer irons than "standard" irons, meaning that they don't stop as quickly on the greens as standard long irons.

Here's my statistics:

Using standard length irons (most of my life): Avg score: low 100's

Using single length irons (last 2 years): Avg score: high 80's

Clearly I'm not a professional golfer, and I enjoy the game much more scoring in the 80's vs. the 100's -- my happiness is the most important "statistic" in my book (and that's revolutionary enough for me).

Right. Like I said ...great for you and a few others I suppose. The vast majority of golfers are above a 10hc. If SL clubs were 'revolutionary' as they are to you, then they would be all over the OEMs and selling like hot cakes. They're not because they aren't. I'm actually glad you find them amazing. No problem at all. But that wasn't the question. Gimmick...well....'Gimmicky' is the best I'll give them.

I went to a demo day last Friday, and Cobra had a tent there. I initially tried out their F7 hybrids (I have a single FlyZ 4H) to compare the shafts and lofts. The rep also had some single length irons there:

 The rep had the F7 ONE model in both Fuji Pro 63i graphite and TT King F7 steel shafts, both in R-flex. Both test sets had 5, 7, 9 and GW. For the Forged ONE, Cobra had a single 4i in FST FLT 120 Stiff.

I started with the 7i and hit all four irons in the graphite. The ball jumped off the turf with all four lofts. The 5i struggled to keep up with my normal 5i distance, despite stronger loft. Although the graphite shaft was somewhat light, it felt well balanced. The ball went higher than I would like.

I then hit the same shots with the proprietary steel shaft. It weighed 107 grams, but not unusually heavy. Again, the ball jumped off the turf. I especially liked how well the GW jumped the ball with just a quarter swing.

I then tried the Forged 4i with the 120 gram FST FLT (flighted) shaft. I hit about shots. Two were solid, three were fairly low, and three were weak, pushy fades. The shaft was just too robust for me. (Note: Cobra does not recommend the ONE length 4i unless you have driver clubhead speed of 95 MPH.)

A 20 MPH headwind kicked up as the reps were starting to shut down. I tried the steel-shafted R-flex F7 ONE 5i into the wind, and it didn't go quite as far. The 9i, on the other hand, just flat hit the wind wall and went about as far as the GW had flown in stiller breeze.

If I got them, I would need a shaft that would bring down the ball flight a bit. Maybe the Dynamic Gold SL (104 grams)?

I would say that the single-length are more than a fad. It's a matter of identifying the early adopters of the technology. I would suspect that the irons will gain early inroads with both younger golfers, and frustrated senior golfers. (Younger golfers, if underemployed, may be short on funds.)

I've never tried single length clubs but since learning about Dechambeau and his single length irons, I've been dying to try them.

I'm a high handicapper (used to be mid :( ) but I've always been pretty handy with the shorter irons in the bag - from 8 down to wedges. If I'm having an 'off day' with my irons, it usually comes from the longer irons, Stick a shorter one in my hand and the swing feels fine. I don't think the loft of the club has any effect on my swing, it's certainly always been the shaft length...

Because DeChambeau has been just knocking it down lately.  Huh?

The feedback I get is that Edel does it best -- apparently the Pederson (?) shafts have various kickpoints throughout the set.

I bought the Cobra f7 one length irons. Sent them back after a couple rounds. My ball flight was lower with them and my ball would not hold greens.

Nice distinction.  I'll give you "gimmicky," but then, metal woods were gimmicky until someone on tour won with them.  Lob wedges were gimmicky until Kite won the U.S. Open.  Lofted hybrids were gimmicky until Yang came from behind to beat Tiger in a major.  Armlock putters were gimmicky until they salvaged the careers of several belly-putting pros.  DeChambeau makes SL irons 'gimmicky.'  They'd seem less so in the hands of a less eccentric pro.  The worst you can say about SL irons right now is that they're like chippers or easy-out wedges:  Disdained by the seriously talented but a godsend to the less-skilled.  I expect that, ten years from now, many more pros will be playing single-length irons.

Considering how few irons a person is likely to have in their bag these days...the single length concept is close to being a misnomer.  I carry a 4 thru 9.  Granted the pigeon wedge used to be a 9 iron and the gap wedge use to be a pigeon wedge; but that isn't nearly as many clubs as it once was.  If all you are trying to do is cover 100 yards...why not do it with loft rather than length?
