RE: Getting rid of the crossbow.....
I have owned both and prefere a compound as well. When you really compare the two the Xbow really does not have that many advantages over a modern compound.
Apple, I don't know how to break this to you, but there are several bows on the market that devolope more energy than some Xbows do. If you have a long enough draw length some will shoot an arrow that is longer and heavier at the same speeds with a 70 lb draw weight. And do it more accurately and quietly to boot.
I'm not going to say your average set up can do it, but it can be done. You better have a big bank acount making a wager like that. You might be paying a few thousand dollars at the end of it. My Bowtech Mighty Might has an advertised speed of 324 fps, that is faster than some crossbows are. I have personally had mine close to 300 fps with 60lbs of draw weight and 26 inches of draw with a short light arrow.
If you could, this would be something I would be very interested in knowing. Shoot your crossbow thru a chrono and weigh one of the bolts for me. I'm curious as to what the real performance of these things are. I know my current bow beats the crap out of my older barnette that I had. And it was a 150 lb compound. I might do some research on my own as well.
I'm not trying to be a prick, just letting you know that there are some modern compounds that can acheive what a crossbow can.
