I too am a meat hunter, and the deer in my area are hitting the corn and the soybeans pretty hard...plus the hostas, boxwoods, azaleas, roses, and other ornamental plants from the estates situated among the farms.
I'm pretty close to you and the deer over here in Maryland are in full rut right now...last night while driving home I saw two bucks with huge racks moving out in the open in fields...not caring what was happening on the roadway...ya don't see them doing that at any other time than the rut.
I try not to shoot the big buck on the farm if I have a choice between him and a doe, or a young buck. He's the daddy of all the nice young does and young bucks, and I'd like him to make lots more... plus he likes the farm and keeps the does in the area. If I drop him the buck who replaces him might have different habits, and make my hunting harder next year.
I found that an older animal, especially if shot when adrenalin is flowing, is tough, and may not taste too good. I've never been good at "aging" meat, so I'd try to avoid that. For example, my boss brought in some venison from a buck that he shot right after it had finished fighting another buck during the rut...he shot the loser... very tough meat.
Finally, there are lots of different ways of cooking up venison, and I'd recommend that IF you get some that's very tough you try a recipe designed for cooking tough beef...slow cooker recipes tend to be such...and they should work for tough venison too.
As for very "strong" flavor...it could've been improperly processed, or maybe it's just from an animal that has had a poor diet. Curry is one way to "dress gamey meat"...and Ted Nugent in his book
Killit & Grill It has a ginger based recipe for strong tasting meat. Mr. Nugent writes that if that recipe doesn't make the meat edible, it was never going to be edible...
