What did you change? Angles? Width? Highback lean?
Any change can make things weird. You want to change things gradually to let your body adjust. Some settings/agles might not agree with your knees etc.
Thanks for your reply!
I adjusted everything. I changed the highbacks so they are parallel with the edge of the board, the biding width i kept the same, i did move the rear up a bit so i didn't get any heel overhang. and the angles i messed with a bit.
