Shiloh,
I just use a good 3/0 flat waxed nylon thread for all of my tying. It looks great and you can really put pressure on it while tying to hold your marabou or kip down. It does not tear and break like other threads. It also takes head cement well.
Cabelas has it as stock # TW-31 - 0661 It is about $3.00 for a couple hundred yards of it.
