Big:

Those string leeches weigh 25gr each! Thats a whole lot of extra weight on your string! I'm not sure what those speed nocks go weight wise, but its probably about the same as the brass nocks.

Here is what I would try.

First, I think that most BTs, if not all, have a rear mounted stabilizer hole. So get MeanV2 to make you a CSS... money very well spent. That will take care of the need for string leeches, which of course, slow you down a lot.

Next, if you are using brass nock points, scrap 'em. Greg/MO did a thread not long ago on tying your own nock sets. I'm sure you probably know how to do that already, but just incase, its a good reference.

Additionally, I have noticed that sometimes adding weight in certain places on the string can make a bow faster. This is the only thing I use brass nock points for. Try putting one or two brass nocks on the string right where the serving ends/starts on the top and the bottom. You have to experiment a fair bit, but sooner or later you should hit a sweet spot, and that will maximise your speed.

Just a few thoughts to try out. Good luck.
