Rob, I bought several spools of that nock-tying thread, as well as my release rope, from a lady who goes by redcharm over on ArcheryTalk.com... she's got a thread in the classifieds that usually stays up near the top. Very reasonable, too... I think it's a couple bucks or so for a spool; that's why I said use the stuff liberally.

I know from experience that my Bowtechs are going to tune pretty well at an almost level nock point. Most solocams are going to start somewhere around 1/8" above level... If you know so that you can start fairly close, you can make the final tuning adjustments with your rest. For instance, I started off with mine exactly level using a laser and levels (see link in how I do that:http://www.huntingnet.com/forum/tm.aspx?m=1684829&mpage=1&key=quick%2cbow& amp;#1684829), but ended up doing some minor fine-tuning with the rest's adjustments after shooting through paper and following up with walk-back tuning.
