I think I already know my answer, but I figured Id ask the experts before committing to buy anything. Here are the contenders.

They are both petite, so nice and small. Howevever, here is what gets me. They both cost the same price, yet the Dual Core has a 5 r-value rating while the Diversion has a 4.1 rating.
Im going to do spring and summer hiking 90% of the time with an occasional fall hike here and there. I will admitt, when I say fall hiking, I mean I wouldnt mind venturing into the month of Novemeber. This being in the middle of Wisconsin. So heres the thing they are both the same price which really boggles my mind with the R-value difference. Still the freaking Dual Core weigh 10 ozs more, so really it just dont seem like it is for me.
Personally, from my standpoint, I think I will do just fine with the Diversion and even that might be a slight overkill especially if most of my hiking will be done in late spring and summer. Can I get an verdicts from anyone else. Thanks.
P.S. I dont like the Air Core mattress which is slightly lighter than the Diverison, so please dont throw that idea other there. Something about the pad just doesnt feel right to me.
