I went the opposite direction. I have a W80DM x 40" pitch, it came with the airplane. That's just about perfect for 150 on a Cub, and favors take-off / climb. It's about half the weight of the Borer, but gives up performance. My "just right" Borer is an 82/42 and will out climb and out cruise the Sens. For me the performance increase was worth the minor weight / CG penalty, but my CG wasn't bad to begin with. In my case I would not go back, but I've seen some 12's with pretty dismal numbers. I suppose it depends on how far north your CG is, but I think you'll be disappointed in the lack of bang for your buck. If you're not operating commercial and not the worried about ramp inspections, I'd look seriously at a Catto 82x39. I have one and its perfect. It performs identically to the 82x42 Borer and weighs a couple pounds less than the Sens. It's the Goldilocks prop. There's just that pesky certification thing.....but lifes too short. Screw it, I'm running the Catto and loving every minute of it.
-- Other things to consider are a Niagara aluminium oil cooler, Skytech starter and a lightweight 20a alternator, especially mounted to the accy pad.
