Junkyard surprise was a bit over the top.^^
Though now it's just savescumming, not sure we gained anything there.
Maybe a feat that reduces final encumbrance by 15%? As in, if your 130% is still 95% total, it's then reduced to 80%?
Or, more interesting, a feat that's "33% less effect of encumbrance on movement".
I read a few discussions on the "War of the Roses" forums about movement in heavy armour, and as it turns out, a chain hauberk + Plate Harness (+ accompanying leather and undergarments) doesn't actually slow a trained soldier down that much.
It might put a strain on their endurance and fine motorics, but you can still reasonably move.
Then again, Underrails armors are very effective against automatic firearms, which can't be said of actual metal armor.
