He didn't touch the heel pad, I made sure he didn't. He cut the heel on the weight to match the 10 because the standard 11 has a taller heel. This way I can use 10 series weights or the mod 11's I have now. Just tried the stock 100/275 without the glide washer. Engagement is at 3850IF I FALLOW THIS RIGHT ..A 10 SERIES WEIGHT IS NOT TUCKED..11 SERIES ARE. SO EITHER THE WEIGHT IS CUT ON THE HEAL OR THE WEIGHT STOP IN THE MOVABLE SHEEVE WAS MACHINED OUT A BIT TO DROP THE TIP. EITHER WAY YOUR GOING TO LIMITED ON SPRING SELECTION. WHAT IS THE ENGAGEMENT RPM ANYWAYS?
