I have a Callaway Epic Max LS and the Logical One Neuro X Tour -- those will start the year as my first string, and they're both in the 47" range. But I have a lot of heads and shafts sitting around. Have a square Adams Insight a3 Boxer, a Juggernaut Max, a Yamaha UD+2, a Grand Prix GP Max One Minute all waiting to get shafted with something. Then there are the old friends that get dragged out from time to time. I have a few classics around 44" -- Alpha V2 425, Accura Fireball, Yamaha D201 that I'll carry as my shorter driver.
