I've been playing the AD333 for a year now and it's the all-around best ball for my game I've ever played, at least that I've purchased (bought some at 2-for-$25 at Dick's).
As background, I shoot in the 90's, have only broken into the 80's once, but typically have quite a few holes where I play a lot better than my average would indicate - I am very inconsistent and usually have several snowmen or worse on my scorecard and may make more than the average number of 3-putts, hence my scores that say "mediocre golfer." Not playing more than a couple times a year for five years devoting myself to the parenting-a-young-child-thing has been my biggest problem. When I'm hitting well, with my old balls (usually Nike Power Distance or Mojo, TM Burner, Callaway HX Hot or Warbird), I was hitting my driver around 275 on really good drives. I can often shape shots when I'm behind trees, facing a stiff cross wind, trying to aim away from hazards, trying to hit a draw with my driver for extra distance, etc... but I am not at all consistent in doing this or achieving the desired amount of curve or height to my shots.
However lacking in skills I generally am, I have played a number of Pro V1 and Pro V1x balls that I've found or bought in an used ball barrel, and they are my favorite ball. I have hit a 300 yard drive (w/maybe 5mph wind assistance) with a Pro V1 and I can often get them to stop or spin back a bit with wedges or short irons. I like the softer feel of the Pro V1 compared to most distance balls and like how they are firmer and feel more precise than low compression high-handicapper balls like the Noodle, clicking off the clubface on well-hit shots. I feel like I can tell when I've hit a good shot better with a Pro V1 than I can with other balls. I don't play Pro V1's regularly because at $4 a ball, it's not economically senisible for a golfer of my skills to spend that much on a ball that I'm likely to lose within 4 or 6 holes and in spite of hitting more shots that I noticeably liked with a Pro V1, I cannot say my scores are typically lower with them.
The first time out with the AD333 on a relatively flat second hole with no wind, when I wasn't yet warmed up, I hit a draw into the center of the fairway 285 yards out. I hit a 290 yard drive later that day. I've had a couple of 400 yard holes with the AD333 where I've had a gap wedge into the green and on one par-5, I hit driver, hit 9-iron over a tree to lay up in front of a creek, and then pitched 60 yards onto the green. Last week I came about 5 yards short of the green on a short 275 yard par-4 hit with a 3-wood (new Ping G20 - best club I've ever hit).
The AD333 is a harder ball than a Pro V1, but softer and more solid feeling than a Burner, HX Hot, Pinnacle etc.... I've had at least half a dozen 8-iron shots with an AD333 back up on a green and once even had a 7-iron shot from about 155 stop dead. No ball I've played, other than a Pro V1, will consistently back up for me except with a sandwedge. I haven't played many other mid-upper end balls for comparison's sake (just those I find on the course), but despite supposedly being more of a distance ball, I've found the AD333 has really good feel and stopping ability.
The AD333 is a tougher ball than a Pro V1, about the same as a Pinnacle as far as resisting scuffs. I'm not a good enough putter to notice much difference (I've got a STX putter with a plastic inlay face that's pretty soft, so most balls putt the same for me).
I also like the fact that I'm always the only one on the course playing this relatively obscure ball, so I don't have to worry about someone else hitting it by mistake and later saying "Oh, I didn't notice your Titleist was a 2 and mine was a 4."
However, the AD333 is becoming even more rare these days, as I believe it is discontinued. I should have bought a gross of them when they were on sale at Dick's, as $12.50 a dozen is a heck of a bargain. I've not found them anywhere online except at $20 retail plus S&H and I'd prefer to spend a bit less on a ball than that.
I've never played the Tri-Speeds but have thought about buying a dozen, especially since they come in yellow and I seem to lose a ball every round that isn't hit far from the fairway, but gets lost in with dandelion fluffballs, goose feathers, leaves, etc... and I think I'd probably find them if I had been playing a yellow ball.
If you know where to buy the AD333 at a discounted price online, please advise. I'd like to pick up a few more dozen.
Hope that helps.
