I have had the idea of thinning the Paragon, but I'm afraid of distortion and it's a lot of $ for a tube.
I'm sure the bike shop would let me use their reamer. The main thing is not to ever go backwards, no matter how tempting it might be.
Yes never go backwards. I do have the ST reamer and my seatposts fit much better than on any mass produced bike I've owned where they slipped down if you weren't within about 1Nm of the maximum torque the bolt would take. With a proper fit you don't need to do it up that tight. I'm not sure this sanding hack would work so well on an ST.
The Columbus tapered HT has a system of sleeves you braze in and then drop bearings into. No reaming required and no press fit. Seems to work pretty well but difficult to face. I'm also not a fan of those beer can HTs.
