right now, i own a Viper pro series that i got as a promo from marlboro cigarettes a couple years ago. i replaced the shaft this year, but for some reason i dont like the players shaft i bought for it. the joint is a 5/16 x 18 13mm flat face. i was wondering if its worth buying a good shaft to use with the butt section. i also own a cuetec jump/break 3 section cue stick that is all graphite that i use primarly as a shorty sometimes and break cue other time. does it make sense to buy a different shaft to use with this rather than the graphite sst that it came with if i also wanted to use it as a shooting stick? im trying to find something i like that will compliment my game without throwing away money. i'm a APA 8ball player that plays for the most part on 7 x 3.5 bar tables. i know its not the stick that wins the game, its the player that wins it.
