old driver goes further, straighter but goes REALLY high

At the beginning of the year I purchased a replacement driver (Nike Covert with the factory Stiff shaft) to replace my ~3 year old Cleveland DST300 driver.  On the range and in the simulator, the Nike driver went straighter, and had a lower more penetrating ball flight.  However, in actual play the cleveland just played better.  The problem is that the ball would go WAY up in the air would go further, but then would just fall straight out of the sky.

I think that alot of this is regarding the amount of backspin produced by the club.

Also, the Nike is much more sensitive.  My miss is an out to in swing that causes a slice with the nike, but a high "strong fade" with the Cleveland.

The Cleveland has the stock Mitsubishi White 44g shaft.  The Nike has the stock Kuro Kage silver shaft.

Is the shaft or head causing the additional backspin?  I don't know that I am ready to make another investment in a new club.  My driver isn't holding me back right now, my short game is a larger problem.  The purpose of this conversation is mostly just for the sake of conversation.

Since they are calling for possible snow flurries this week, I get to spend the next several months talking about golf instead of playing it :(

I am not seeing what the problem is exactly.  So with the added height the old driver is going farther?  I hit my driver pretty high now and love it!   It surprises some people now how high I hit it.  But if it goes farther and straighter, there is not really any issue that I can see, only positives.

Probably a combination of a lot of things.

New golf heads are then to spin less. The golf shaft probably has something to do with it as well. Loft will increase spin as well. So if you hit a 9.5 versus a 10.5. Also your swing, how the club weights can impact how you deliver the club.

I would chalk it up to a culmination of things.

Also, if your swing speed is lower, you want more spin to gain carry. At slower swing speeds, there is just not enough pure velocity to gain the maximum carry, so spin helps.

Thank you - I don't think that I have a swing speed problem.  On my last round, I was averaging probably 235~240 with several over 260 and one at 274.  So distance is not an issue.

As for the loft, that is the weird part.  The Cleveland is a 9 degree, and the Nike is set at 10.5.  I think that the Nike has a little bit stiffer shaft (Kuro Kage 50g vs. the Cleveland made for - Diamana red 44g.

The other thing is that, I have used both clubs enough to learn that the cleveland is better off the instep of my front foot, and teed up a little higher (1/2 the ball above the grounded club) than the Nike which is better off the inside portion of my heel and teed up (1/3rd or a little lower above the grounded club head) So the AoA might be higher since I am hitting it more on the upswing.

My driver swing speed is on a driver is 95~100mph with the best results when I swing around 95~97.

Again, as the weather gets colder, this is golf's version of bench racing (in between checking SWA.com for bing rates to florida to go play for a weekend)

Its probably the shaft, KuroKage is a mid to mid high kick point, with a stiff tip and stiff mid section

Red has a mid kick point with a softer tip section, and softer mid section.

So between the two, and the fact that the Red is 10 grams lighter, your probably looking at it being the shaft. A softer tip and lower kick point would tend to see higher launch and higher spin. Heavier shafts are generally stiffer than lighter, just more material.

Any recommendations for a shaft that would go into my Covert?  I do prefer the look and sound of the Covert.  So if I could find a pull and put an adapter from ebay (without spending a ton of money) I would be willing to give it a shot.

Thanks

Well both drivers should be better hitting up on the ball, more towards just above center on the club face. That is were optimal launch conditions are found on modern drivers. So teeing up your Nike lower, and moving it back is counter productive. You want to hit both with a positive AA.

As for which shaft, tough to say. That KureKage is pretty stout. I do think it might be to much golf shaft for your swing. If you want a covert, the economical thing to do is just trade yours in and go with the KuroKage Black instead of the silver. Its a bit softer than the silver. But I would go get fitted at least. Honestly there are so many options out there, I really can't give you a straight answer on this one.
