I built up the ARE 12' 5/6, and yes it is more of a 5 than a 6. However that is a two hand 5 weight, so it's more like a 7 weight Single hand. Mine is on the IM6 blank but the UHM has a very similar grain window. I use mine for steelhead and it is perfect for fish in the 3 to 7 pound range, and is a lot of rod for trout. The next rod I plan to build is similar to what you are looking for, a two hander equal to about a 5 weight single hander, and I am thinking about the 3/4 although I am leaning towards 11 feet myself.
