I went with 13" to add a little height and figured it would increase dropping into the corners. I'm right around 6' so I'm not on my tippy toes anyway. I leaned on
@1olbull for info regarding talking to someone with personal experience w/ the 444s. He's a big guy too and ran the HD springs for awhile before going to STD springs which he stated he likes much better. You can always pick his brain too.
Not sure what you're saying about the second choice comment. According to Progressive's website, the correct P/N for your bike w/ 13" height, HD springs, and black is 444-4221B (same thing I bought for my '17 Roadster). I agree about Progressive emails not getting returned, I did however call and they answered the phone, so there's that. Like I said, but before Friday and get the fork springs free, so it's basically another $100 off.
