True on all of the above shoot4thrills.
I will admit that I haven't exactly thrown away the training wheels yet, and I've got one hanging in my garage that meets the description you just mentioned. I shoot 5.5gr. pr. pound HV's with it and it's ripping them out at 303fps. I don't expect, need, or want that from my Grizzly, it's an entirely different animal that I consider to be finess rather than a full draw short range rifle in comparison.
I'm still waiting on my first trad kill and I may not ever give up my wheelie, but I'm sure enjoying this season hunting exclusively with my Grizzly and I can honestly say that I haven't been this excited about archery season for quite some time. Maybe it's just the anticipation of taking an animal with something I never have before, or the basic simplicity of using pure skill as apposed to high tech? I don't really know what it is, but when I get my first kill down it will be like my first deer all over again. It's like waiting on Christmas when your 5yrs. old.
BTW- Your set up with your Predator is roughly the same as my Grizzly as far as arrow wt. pr pound of draw, and yours is even a bit heavier. It seems like your getting some good velocity from your set up for shooting heavy weights, that must be one heck of a hard shooting outfit you got there? You should post a pic of it here if you don't mind. I'd sure like to see it.
