HELP! Technics SL1200GR/Benz Glider Anit-Skate Setting High

I just mounted a Benz Micro Glider on a LPGear Pro Headshell which looks like the standard Technics headshell but is not up to the same quality as an original and I think is lighter.

When I first mounted it, I couldn't set the VTA correctly because the cartridge height was too low.  I had a plastic "angled" shim that I had from an old Dual DD turntable I had in the late '70's.

I installed that and was able to get the vta set OK.

But, when playing, I noticed that if I set the stylus down at the end of the last song on a side it would just fly into the label area.  I usually set the anti-skate at about 10 below the tracking force.  For the Glider the tracking force was set at 1.9 so I set the A/S at 1.  I kept increasing it until the cartridge would not fly into the label.  I ended up at 3 (the max.) A/S force.

I've never had this happen before.

I tried adding weight to the headshell and resetting everything and the anti-skate setting doesn't change still high.

I've often read many times that people usually have the A/S set too high even when they have it set to the same value as the tracking force.  Mine is set at least 10 higher?

Any ideas?

Thanks, Nick
