Well i hooked up with Abe last year and bought one of his slug doctors.I haven't seen a loose rack since.so recently I decided to tighten my cloth on my table.Had to take off the slug doctor so i decided to draw the lines on the table(head string and foot string) and decided to try my delta 13 again.Well for the life of me i couldn't get a tight rack.I tried and tried but no use.Well needless to say i put the slug doctor back on and i'm back to tight racks everytime.Right now abe has free samples of his slug doctor on azb and you really should try one.what do you have to loose.i love it and you will too.....thanks for listening....rick.
