epoxy resin??? who makes the best??

I did heaps of research on this a couple of years ago....and have tried several brands.
I reckon BoteCote is great to work with.
It's not as toxic as most other epoxies...I've glassed a few boards with it and used it for heaps of other stuff and it has never made me feel crook like a brand I wont mention did....needless to say this other brand gave me headaches and had me parked on the porcelain throne for hours....just had enough time to get vacuume pump going.
BoteCote also has a non yellowing hardener that is good for a board that is not going to be painted.....only problem I've found is that it is not the clearest of resins.....it's kinda a very little bit milky looking, not crystal clear.
One of the Aussie guys who's been doing composite sandwich surfboards for years also highly recommended it.
Kinetix sounds pretty good but I haven't tried it yet.
Resin Research from the US sounds like great stuff but not sure you can get it in Oz.....couldn't when I last looked into it.
Good luck.
