I would go with a 60#. The draw on the Pat DC's is a little rough, which is why the thing IBO's at 334 f.p.s. I have drew the Pat DC back at 70# and there is no way that I would be able to do it when I am sitting out in the cold temps!
Same here and I am a bit larger in size than BM...
A 60 lb Pat DC should be putting out plenty of KE with most setups. Now, if you were talking about a Freedom Cam Bowtech then I would probably recommend the heavier weight since the draw cycle overall is much smoother.
