Yes, I got the XXL, with the F booster, along with the planted bracket. I wasn’t that worried about heated seats but the Mrs insisted, and the heated seats are in stock.I know how you feel, the pair is more than I paid for the 80 actually. I suppose they are my single most expensive mod. I'm cringing at the price of bumpers, and then realize I have more in my seats... I only have ~ 90 miles in them, but they feel great so far, and they are just the perfect seat for an 80 I think. And probably the first seat to fit my back well (I got the XXL's) since that's where all my height is. Did you get the Planted brackets ? They are the only ones I have experience with, but they were perfect.
Enjoy !
