I've never owned a cuetec, so I can't offer any first hand knowledge from that
perspective. Some folks obviously own them, enjoy them, and supposedly their
construction makes them suitable for extreme-changing weather condition storage.
I did have the opportunity to use a cuetec once. A somewhat-OK, maybe B-, player
in MA, who by the way, resembled Earl Strickland but was shorter, used one as a
break cue.
He had the tip filed *EXACTLY* flat. His theory at the time was, that it was the hardest
hit he could find, without feeling like the he might be damaging the cue when he hit the
cue explosively.
The flatness gave quite a large margin of error for tip-to-ball placement.
Anyway, those are some helpful tips.
