Best to find a sleeve to find out. Club head speed is one variable, but so is the amount of spin you apply in your swing. If you are already low spin, low launch, ...probably not. If this were the case - and we can't tell in a discussion, you might do better with the standard X. if your ball flies high and "drops out of the sky" then the Left Dash X would work.

Not to say the V isn't already your best option. Just noting the usual variables. The other alternative is to find a Titleist ball fitting, but a sleeve is a lot easier to find. No one ball offers the best solution for all players.

To note, I'm not anywhere near your golf swing, but the absolute worst Titleist ball for me is the Left Dash. I'm low launch/low spin already.

Really difficult to say with any conviction as depends on how you deliver the club and your ball flight distance.

Best advice is as above - get a sleeve of V1 / V1x / AVX and LD and try them all on a quiet course one by one. I am a high spin player and settled on AVX/V1 as I couldnt stand the feel of the left dash, however, I did find it went a little further than the prov1.

I would also say, please dont neglect the short game impact too - start there and work back to the tee with whatever ball suits you and your swing best.

Good luck and enjoy!
