Okay, most of that I am not disputing. And I totally agree this guy should submit a video of him on a bike at those coordinates to this thread prior to doing anything so stupid as buying a bike based on some guy's name he doesn't even remember and who didn't get a video or images of him during his fit.
But let's assume that his fitter got him in the ball park. For maximum flexibility, I would recommend to him a large Shiv TT with, say, a Profile Design Aeria Ultimate. Or, large Shiv TT with Tririg Alpha X pads at center, ultra low duster cap, and 20mm of pad spacers. This would allow him to go 20mm lower, without dismantling anything, or as much as 50mm lower, with undermount. If he so desired, he could go as high as +40mm with just pad spacers (same reach).
Alternatively, a Cervelo P4 56 with an Alpha X, pads at -10mm, and no pad or stem spacers. Or keep the stock Ventus, but that's going to provide less in the way of flexibility.
I provide consulting services on fits and bike purchases. PM me for details, my current work is all done pro bono. They should really pay me for this though
