Here is a unique piece of advice - pick a cue, pick a tip you like to install on that cue- play with that cue every single time and Forget about deflection, etc. - just play man- what do you think the very best do? Worry about thus stuff? Deflection etc. are all inherently adjusted to by the shooter over a course of time using Any cue- the rest is ALL Marketing hype to get you to spend money.
One of the very best players I ever saw in competition used to get out of his car and walk over to the pool hall about 30 minutes before the tournaments started with an old Meucci "in his hands" - no case, no jump or break cue, nothing but an old Meucci broken down into two pieces in his hands- and he took down a lot of JOSS tournaments in the 90s against guys like Ginky, Frankie Hernandez, etc. etc. - Guys make WAY too much about equipment on this site- you should be concerned with so many other aspects of the game His name was Chuck Altomare - He went # 1 in a lot of Joss tour Calcuttas in the 90s when he was playing real well - I saw him carrying that cue on the streets many times.
