Yes I have, I never carried them before, so picked up a couple of boxes, I did'nt realize that was'nt normal for them, and was trying to find a way to harden them up some, while making them easier to crown at the same time, so they did'nt roll/string up so bad, but not real impressed with them either, altough i don't care for softer tips that much Myself anyway. Some do seem better then others in a box though.
Still get alot of people that want le-pros, and there was a day I used them also, altough not My preference on My personal cue now days either. Too much dressing required to maintain them IMO. I like to press them before installing, and that helps with the mushrooning a bit, but I have many people that are still plenty happy with them.
Some like the WB's from My experiences, and some don't, so I get mixed opinions. Yes I aggree, they do smell like a carraige ride through down town

I like them alright on a break cue, and could shoot with one if I had to. Super pro hards are not bad for breaking either. I'm using phenolic on mine right now though.
My understanding is that there are alot of good tips out there, and I have tried some that i liked over the years, and have more here that I need to try out, but have'nt tried them all. 2 I really like are moori's & triumphs. the triumph has the backer, but I can still make the transistion from the mooris to them easy enough If needed, so I have one on a extra shaft.
Soft tips not sure, just personal experience, but never really found any I liked that much for either playability, or ease of intallation. seems like most I have tried had their own issues one way or the other. Greg
