I run 135 lbs on my stock magnum 360.
It's been said numerous times that 140 is max recommended for an iron core roller. I have no personal experience trashing one by using more than the 135 seat load I use.
Based on the stock 90 lb seat load... you could run the seat load anywhere from there-140lbs.. as long as the rate is there and load...for instance touching 250-260lbs @.400
