I have used a PSE Patriot Pro for years. It is not as fast as the new bows, but it sure is more forgiving. It kills the deer just as dead as the new Bows. I do have to admit, I finally did buy a new bow this year. Not because I really needed to, but because my nephew wanted to get into Bow Hunting. I gave him my old bow, so it gave me the excuse to buy a new one.
I love my new bow (Diamond Black Ice), mostly because it is new. It shoots a flatter trajectory and i can use the same pin for 20 & 30 yards. It is easier to hold back at 80% let off vs. 65% on my old bow. It is very short and compact, but it took some getting adjusted too. After a few practice sessions, I am dialed in.
If my nephew did not need a bow, I would be using it today. I use a whisper biscuit on both of them, Sims S Coil, Gold Tip carbon arrows, and a mechanical release. If you are just getting into Bow Hunting, or are on a budget the old type bows work fine. Try to find someone who has updated the bow with so of the goodies I listed above, and you can get a real bargain. You can even find some very reasonable older style bows brand new for very reasonable prices that come with a complete package.
