Nrobert: I briefly met with Flakwagon yesterday and did some bathroom scale lifting...he has an EB with three links out of the chain and we got readings a little higher than yours.
His top will stay in place where you put it and it will move near the top of it's travel with about 60 lbs. To start lifting it from full down took at bit more than what you are showing above....I think around 140-160 lbs.
He needs more preload on his helper springs.....and the more I think about it longer springs would help greatly as well.
His top is a mid 90's and the helper springs are shorter than the springs in my early 2000's RB top. Any chance both you and Flakwagon can measure the length of your helper springs? I will measure mine when I get back to So Cal next weekend hopefully.
