As for "farkle" I have rarely even used a sling... I use a single bead. Never rifle sights, scope, halo or laser... one time for coon I used a couple galvanized electrical straps to hang a 3 "D" cell light but the bulb blew on the first shot...
I am a simple man, with simple guns expecting repetitive results... Like they say... "Be wary of the man with one gun... he knows how to use it..." I own just a few guns. One being my .22 bolt gun, I have a 336 Marlin .30-30 as my only C-fire rifle and then the smooth bores. I will never part with my 18.5 inch 20 gauge but the rest tend to come and go as funds require...
