I've taken all the advice here and raised the pressure a few pounds from what I ran on my Assegei and DHR. I took the bike out last night with 30 in the front, and 32 in the rear. It absolutely ripped. It felt like less rolling resistance while also MORE grip. The grip-off-jump issue was lessened but not eliminated. I'll have to experiment with other casings, or compounds / tires, as others have suggested in the comments. Thanks all, for setting me on the best path.
Unless I'm trying to maximize grip in the wet I much prefer radial front/non-radial rear. I like being able to break the rear tire loose often and for better or worse the radial rear makes that much more difficult to do. Horses for courses I suppose. I just want different things from my rear tire vs front.
