I used Raka's 127/350 combo and was very pleased. Never saw any blush. I can't speak to the choice of fabric. I used 6 oz. inside and out on the hull, with 3.7 oz inside & out on the deck. The deck is doubled in all the hatch areas, and I added a 3.7 oz "football" patch on the hull. I'm still a few days / weeks away and the first long trip will be next July, so it's too early to tell if I made the right choices. I _really_ like the 3.7 oz fabric, and I'd sure consider doubling that instead of using 6 oz. next time, but that's only based on the ease of handling, fill, etc.
