I've been using the split grip, not the 10 finger grip with hands touching, for 3 weeks regularly. I feel much more of the roll of the right hand at or just after contact and my shots fly high and straight.
I don't have the distance you guys do since my physical condition limits me at my age, but, with the split grip I can really hit the ball 80% of the time straight and that's helped my scoring, if, at my age that is even important to me. I just enjoy golf, good or bad.
I'll stick with it till I can manage to understand the wrist roll better and may or may not change back to my interlocking grip. I'll just have to wait and see. I use the split grip on every shot except putting. My chip and pitches are much higher, straighter, actually get some stopping of the ball on the greens at times. So I'm good with keeping it for now.
