yeah mate--my friends are the same--toluene only--3 times--though they do a mineral turpentine100% soak for 12 hours before --and an acetone wash after--followed by an a/b extraction---this gives them a clean product that when reduced and crystalized returns 92%purity on a gas chromatography

swim likes xyline . but it is because it stays dryer meaning it is hrydocospic(some thing like that help me out tryp)..but then it just might be that he likes the smell better than anything else.

but both are good n/p's
