YMMV.
145lbs. It seems I've settled on 70psi as a minimum, and may try 70/75 F/R on my next ride. I don't feel that it's squishy, slow or vague, but I do notice at 70/70 it absorbs the road bumps much better than when I tested at 80/80, and didn't feel appreciably slower (set a few PRs on Strava segments on 70/70)
