It really depends on what you consider light, fast, heavy, slow.

Your numbers to me are semi heavy and semi fast, not heavy and slow. Maybe remain the title, semi heavy. [8D]

Heavy, now go up over 550 grains and slow, down to let's say 240 fps. It's about FOC, matched sets (arrows/bow), more than adequate fletch and tuning.

Seriously Don, congrats on the setup, I bet it kills the deer as dead as last years setup.
