I've been using London, I'm sure there are better options out there, but it works quite well for me. It's like $70 a case though.
Used some Colibri stuff recently that was horrible. Might as well have been dollar store crap.
I always hear good things about Vector and Ntane, but have yet to find them locally.
I've tried solventless, I find scraping the bags to be more work for less yield. Could be because we use bud, but I'm not sure. Everyone I've talked to about ice wax has been using trim.
The quality is there, but it's horrible on a nail. Probably end up just making hash candies out of it.
