Before you get carried away.....
You have a "really nice bow".....
I've been at this along time, and everyone here know I'm an old Grizzly fan!!! The Bear Grizzly has been around for well over 50 years!!!!! It was built as sold as the "working man's bow". Kinda like a Winchester model 70 was the "Rifleman's Rifle". When it's time to hunt... I always grab my old Grizzly.
There are alot of great custom bows out there!!! Each of them has their merits, and I have had a few custom bows in my time. I won't say any of them are "bad" because none of them are!!!!! However... They ARE (usualy) VERY EXPENSIVE!!!!! Truth is, unless you have been doing this awhile, and shooting ALOT of differant bows... You're probly not going to be able to tell the differance.....
Shoot what you've got, learn what you can, and save your money for ARROWS!!!!! You're going to use alot of them!!! LOL
Just one old woodchucker's thoughts.....
