I'm sure you'll do well as long as you are not an arrow junkie like our addict Squirrel. Many guys do ok with them but they do not shoot a hundred or hundreds of arrows per week. Hundred grain heads are good for mulies and black bear and at least a 125 grain for elk along with a heavy shaft as well as being up close and personal like twenty yards. Use a cut on contact non-mechanical broadhead for elk.
Sorry to hear about your injuries and welcome to our family! I hope you have fun here. Don't take the ribbings personally, we don't know any better! LOL!
Hope this helps.
