I would do the cantalever barrel and put a 1 to 5 power or 2 to 7 power lighted cross hair scope. You will have the best of both by being able to have a lighted site to use and some power for that 100 yards or more in the trees and branch's. It is nice to see a shot around a branch rather than hit something can deflect even a slug and if you practice and see a monster at longer range you do have some power to turn up. Also with a cantalever mount you can change barrels for bird hunting or clays and not change the point of impact when the rifled barrel goes back on. A scoped rifled slug barrel can shoot 150 + yards easliy if you do your job but still see that deer at 20 feet on 1 or 2 power.You can get some scopes for shotguns that have range marks on them to that can help with distance if needed and light the cross hairs in red and green if needed. Give a low magnification scope a try, you loss nothing to a dot scope and only gain the ability to see a deer better at the longer distance.
