Same here. I run my XL80s on SW1 and they've worked fine. While I was at Rausch Creek a few weeks back I had a weird issue where the XL80s melted against the LP9s. Not sure how that happened as I only ran them for 1 run so far. I pulled them apart and they worked. I've never had an issue and i've had them on for a LONG time at previous events, and in the summer. We had 30 degree temps and lower and still had issues. It's weird that you also had a similar issue Cigar with them. Now I had also been messing around under my hood the previous day, swapping out some fuses in my upfitters (i plugged a laser light into the wrong upfitter to test something quickly not thinking and it popped the fuse).
