Ended up settling a bit. I looked at the R1 but it was a little too lightweight. The gridded fleece is not as warm, though, it depends on what you're looking for. I wanted a bit more warmth.
The Melanzana fleece turned out to be a little too heavy in the end.
I ended up making a sacrifice- Windproofness. Instead, I'll supplement my fleece with a windshirt. So, I won't need adjustable cuffs and hem because I'm not trying to lock down against the wind. Overall, I save weight.
The fleece I got is an Arcteryx Caliber Zip Neck Sweater. It weighs in at 10.9oz, versus the Patagonia R1 pullover's 11.3oz, so I actually save a little weight and this material is not gridded. It feels thicker and warmer for no weight penalty (but you have to pay for it.)
Still, I slipped underneath the $100 mark by finding this on sale. It looks sharp, too- added bonus!
