Love that wrench lure!!! Bet you have caught yourself many a mechanic with that set up... Just remember to let the big ones go, they are the breeders.
Anyway, to the op... If your knot change is working out for you, awesome! What brand mono are you using? I wouldn't use braided line in super clear water with spooky trout. Braids have thier place, but trout fishing isn't usually it.
