I have no data to prove this, only my feelings and the feelings of other team mates at the time.
When I was sponsored by Freak - they gave us our choice of tips. I had many tips as well as many other players on my team.
Although length seemed to make little difference - the All American tip was noticible more accurate than the Freak tip. These tips differed in thier hole patterns and hole size.
Again, nothing scientific - but I would be willing to wager B's kidney on the results of a scientific test.
