it seemed so tight in the stem with one jc41 that it never occurred to me to have two jc41s in there. i'm going to have to give it a try. that would allow me to eliminate everything under the calpac by running directly to the nose cone from the stem. with the 5 port ew90 there's more than enough room for the dfly there. if you have a 3 port ew90, you could bridge the dfly (fd -> dfly -> ew90)
