Quick update as I realised that UK Mat Surfers have been telling all the news about the 5 Star Generals and I'd forgotten to share it on here.
I'm doing the 5SG in both 70/70 Free-Breather and 200/70 Wheezer models now. I'm also doing them in three sizes, Small (fits riders from 5'4" to 5'8"), Medium (fits riders from 5'9" to 6'1") and Large (fits riders from 6'2" to 6'6").
You can get them in the UK Mat Surfers online store.
I'll be building these every couple of months or so in between custom mats. If you want one I'd suggest getting on the UKMS Mailing List.
