I agree Donny.. and I'm sorry, but this could be one of the most pointless debates I have ever seen on this forum !..
Let me elaborate..I personally don't think it matters, if you're 6' 9'' or 4' 9''...The number of contact points with the table, should be completely insignificant !..Any accomplished player, worth his salt, has already acquired the best position at the
table FOR HIM, for any given shot.
Whenever possible, I always felt a palm (or at least the heel) of my hand, gave added stability when practical to do so...There are so many different layouts, and ball positions, (over a ball, off the rail, etc.) that even that simple manuver is not always possible..Its just there for you, whenever practical.
Closed bridge, or open, also will have some bearing on this..Most good players use both, depending on the shot requirements. So for someone aspiring to improve, I firmly believe you are much better off concentrating your efforts on being comfortable at the table, than trying to limit yourself to ANY particular regimen...If you watch the better players, you will see that whatever their contact points are, they look solid, comfortable, effective AND productive..
