What method do you guys use to select a good Lepro. I did a search and found some good advice such as choosing ones with a smooth back, using 15mm as they are cut from a different section, sanding the back, dropping them in water and dicarding the floaters. I will try these methods, but are there any other tricks of the trade you guys are willing to share. I'm not being cheap at all as I've tried the Kamui nd Everest tips (I did like them), but I just prefer the feel of a great Lepro. Thanks in advance.
