Once I replaced this with a pulley my 'assist' weight for one armers has gone from 10kg to (ahem) 20...

This doesn't make any sense, a pulley would reduce friction so more of your assisting load will be assisting rather than overcoming the friction of your rusty hook arrangement (aren't you a scientist??). You should need less assisting weight, it would seem you have had a massive power leakage!
Ahhhh, I assumed the assistance was attached to a belt/harness.

The friction of the hook would increase the amount of force needed to lift the weight... So A low weight will feel heavier....
