I think they both would work, but you did ask for a choice. I think the pink (and I’m not a pink person) looks nice but it may be a little overkill on the “overall” pink scheme. That said, I think the grey would look nice since there is gray in the paint. Also, the gray won’t show the dirt/wear as easy as the pink would.
I guess I would go with the gray, but hey, in the end you have to live with it. BTW, what’s wrong with the white seat in the sig pic, you just looking for a change?
I like the grey better. The pink might be too much pink...??? But the real question is, what color is the skull going to be on the seat!! LOL Three skull minimum in Massachusetts...
