Snowman69, I am using 2 bows, an XI Force One and A Parker Hunter Mag. Both bows are shooting around 260ft/sec. Couple of points here, #1 I don't need all the silencing crap on my bows because I shoot a heavy arrows 489grs that include a 130gr 4 blade muzzy. And still get 260ft/sec. Does this set up work? A ram at 55yds and no range finder! And many elk! Both these bows are single cam bows. #2, I used twin cam bows for years and a single cam bow is easier to tune. If you go super high speed and many guys are, you will beat up your bow limbs, and stretch your strings so you have to retune and replace strings before I will. And the price you will pay for a bow will be a lot more than I would pay. You will not be able to kill them any more dead than I can. You asked for opinions, this is mine.
