Thanks Eric -- Unfortunately I don't have a photo of me in the position Jim put me in (the coordinates I gave you). Also you're right, I screwed up the saddle height, current saddle is actually 790 (just measured it).
What I do have, is a video of me on my current bike (which doesn't accommodate my new position) in a critique my fit thread (which you've critiqued) here: https://forum.slowtwitch.com/forum/?post=6964186. The position is decently comfortable on a trainer but it massively sucks outside, but I feel like my weight balance is too far forward over the front of the bike and want something with a longer front-center that will feel more stable, where I can just lock in and hammer. I don't have X/Y numbers from the old fit.
Jim's new numbers are: X=511 (to tip of pad, 550 mid-pad), Y = 637, saddle = 811, Z (center to center pad width) = 175.
If it's helpful, my road bike BB to grip reach is 634, BB to car reach is 501, and handlebar stack is 634. I'd love for the pursuit position to feel kind of like riding on the shifter tops of a road bike. Is that reasonable?
One thing that does worry me a bit is riding a Size 58, or an XL. Man, I'm only 5'11" on a good day. It just seems like such a big sounding bike. I called one shop to ask about availability of a size XL P3X and 59 P5 to test ride and compare them, and he was like -- "dude, no way that's the right bike for a 5'11" guy" but I mean... Jim is Jim. I'm not going to quibble with his numbers and I felt powerful and relaxed on the fit bike.
Edit (to add): You could maybe talk me into a PX vs P5D. I spoke with cyclenutnz and was I was set against the PX for weight and the bike feeling slow, but I've been doing some reason in this forum, and Slowman seems to think the PX handles more confidently at high speeds on non-technical courses. Then I looked at my projected bike split at IM Mont Tremblant (not exactly flat) and 3 extra pounds costs me <2 minutes. I wonder if loaded up it's actually net faster? In the end I'll probably try to test both but your advice would help. My preferred distance is 70.3 with the usual spring Olympic distance tune-up races, but planning to do an IM (my 3rd, hopefully <11 hrs this time) this year.
