OH, so you have the famous "TRASH MASTER 2000", that's great. And your modifications were the same ones that I planned to do to my T M 2000. I'll let you know how it turns out. But pull tabs at 11-1/2 feet? I easily hit them at that depth without modifications.
I guess I forgot to mention that was 11' 6" WITHOUT the coil. (This is starting to sound like one of those six-pack under the shade tree conversations)
