I'm finding I'm more comfortable in pad-less shorts or my old fashioned chamois than the new "3-D" chamois.

Tri shorts have nice minimal padding, so I want to see how they feel; both for racing and for general riding.

Wet-diaper effect: that's why I swam in plain compression shorts (underwear, really) and then put nice dry bike short/skort on after I got out of the water. The UnderArmour shorts dried very quickly (so did the CWX bra) and by the time I got about a mile down the road I was really comfortable.
