All out OBS.
If there was bubbles in the system the pedal would be softer, not stiffer.
Them NV4500s are stiffer feeling, I noticed that too with the flatbed at work we used to use to haul scrap and plow with.
Good call.. I overlooked the the stiffer part, I was going off of the "releases closer to the floor" remark.
