I have different cues with different shafts, different tips, etc...why? no two tables are the same...one place I play at has very fast clothe and bouncy rails, I have a cue just for those conditions...another place is the exact opposite, slow clothe, near-dead rails; and for those conditions (common to bars) I'll play with a different cue...probably with a Le Pro on the end of it.
I use Le Pros on some of my shafts. I agree they are very inconsistant, but for me, going through a whole box to find one good one is well worth it, and no different than paying $25 for a good layered tip. (drop them on a glass table, or hard kitchen counter, listen for the highest pick clank and rattle, those are the good ones).
When they're good, they're very hard-never mushroom, and can generate more spin than a tobacco company spokesman.
I have a forward weighted Dick Lanz Q that came with a slightly pressed Le Pro, that plays extremely sensitive, which means it does exactly what I tell it to without much effort...which is why I like Le Pros...hand that cue to someone who doesn't have a finely-tuned finesse game, and they'll be completely lost however...OR if I myself play with that cue on fast clothe, or lets say, optimal pro conditions, I'll feel like I'm on ice.
Regardless of what tip you use...if it's well prepared, and well maintained, it will play many times better than just one out of the box, or one that has never seen a cube or pick.
BTW, chalk must be overrated, because the good Le Pros are very hard, and get a smooth glazed surface that doesn't hold much chalk at all (even if you tool them often, after a few games, they'll glaze over real smooth)...I think the #1 cause of mis-cues are MIS-STROKES.
Other tips I use: Moori, Tiger, Hercules, Elkmaster, Triangle...to name a few brands, I'm very picky.
