I'm inclined to think it's more the shorts, if you're not noticing a problem until you're off the bike. This might be the time to try a dab of lubricant, only on the area that's bothering you, if you're not using any yet.

If it's saddle tilt, it's more likely that the nose is too high rather than too low, especially if you're not noticing extra weight on your hands.
Thanks for the idea - I did not think about my shorts chafing me - and there was no discomfort at all during the actual ride (unlike my Brooks). I did not use any lubricant at all this morning, so will try that next time and see if that helps. In a couple of weeks am going to finally pick up some bib-shorts - and while the price makes me want to stick with PI, I think that I want to try another brand.

I am not noticing any extra weight on my hands or anything, and can move around just fine on the bike.

I still don't know what shape the Diva Gel Flow is but it doesn't look/feel wedge/pear shaped to me.
