I don't have a front load and I had considered going downhill and had added 5psi to account for different on bike positions. On rough steep I tend to use my MTB skills and push my weight far back. I had never considered breaking forces. I think that should be mentioned anytime the Berto Pressure drop charts are mentioned. Maybe I'll bump up the front another 5psi, but I hate to give up that nice cush. I think I used to run 60/60 on 32mm tires. (I only weigh 140lbs)
