I find it hard to understand the "blind faith" march to CF cues I've witnessed in my local league. I've seen SL2-SL4 players show up with $400 CF cues, and none of them understand deflection.
An SL7 tried one of these new cues purchased by a lower level player. The CF cue had as much deflection as the new owner's maple cue. He demonstrated that using a full-length shot with maximum side spin, his CF own cue deflected about 1/8 of a ball. With the lower-level's cue, the CB completely missed the OB, deflecting more than a ball's width.
DISCLAIMER: In no way am I saying any of the shafts listed in this poll exhibit significant deflection. My only point, for the bar bangers among us, is to 1) first get good enough to understand and effectively use side spin, and how cues deflect and 2) once there and considering CF shafts, test them before buying them, or at least buy a brand proven to have low deflection (assuming LD is the goal of purchasing a CF shaft).
I know for sure that given how many balls I miss without side spin, I am not ready for a CF cue. I rarely use side spin, and when I do I try to account for deflection but given my SL (5 in 9, 4 in 8), I know I won't benefit from CF, yet.
