I'm a high ball hitter with the driver. The Velocity allowed me to actually lower the loft and squeeze out some more ball speed with less spin. I was seeing 10-15 more yards than my Rogue White. Dispersion wasn't necessarily better, but I felt more confident, so I'm sure I would put more balls in play over time.
funny you mention that, i actually did the same thing when i tested the other day. i figured since the height was so good, lowering loft may give me more distance. it wasn't necessarily a good result, but that could be a number of factors, none of which has to do with the shaft. so it's something i'm totally down to explore further, because i think you're onto something with that thought.
