I realize this is a pretty old thread and nobody probably reads it anymore, but I thought I'd add my two cents. I also haven't read the whole thread so forgive me if it's strayed from where the conversations have gone.

Regarding the stink on clothes, has anyone here tried merino wool? I've recently been making a concerted effort to switch my workout gear to as much natural fibres as possible, as I find synthetics hold the stink and even seem to magnify it.

Merino wool is light, itch free, controls body temperature, wicks like crazy, and doesn't hold any stink (really!!). Most of my shirts and all my socks are now merino wool, and I honestly can't find anything to complain about, maybe that they might pill more.

there might be issues with the mistreatment of some of the sheep may go through, called muelsing (much like a male circumcision, a cutting of flap of skin over their tail to prevent fly infestation). But come 2010, muelsing will be banned, and some companies already carry non-muelsing merino wool.

I might just be talking out of my butt because I hate wearing jerseys, but if it's for just training purposes and you don't care what you look like, then I highly recommend looking into merino wool. Not cheap, but if you look through ebay or sometimes cheap stuff come up on steepandcheap.com.
