i hated snares at first. now i love them. it takes a while to get used to them and they have their draw backs like anything but they are light and easy to set. i prefer to use ones with the rubber hose that slides over the #9 wire support. this year i made up some 30 in rebar stakes with about a foot of #9 wire welded to them. slide the end of the snare up the stake and stomp it in the mud, hang the business end on the support wire and adjust. a few guide sticks and your done. i like the beaver swimming through them rather than walking so i move them out farther when setting pull outs.
a couple draw backs is i dont like that 90% of the time the beaver is alive and the fact that skim ice renders them in operable.
on the plus side is when you miss one they dont get spooked as they dont know anything happened.

i dont think you can over set but you can over lure. in other words if you put in 10 of the same kind of set with the same lure and pinch one, you might get a smart one or 2 after awhile.
mix it up with a few different lures, plain bait sets, and as many good blind sets as you can find.
