Hey Atomic,
It'll take awhile to get used to smaller thread, but you can try this, get some 14/0 Gordon griffith's, tie with that for awhile then that 8/0 will seem like rope and you won't break it. LOL.
I use the GG exclusively and it's a great thread, and it's quite strong, probably close to the 8/0 actually so maybe try some of that trico thread first....
