"How do they fit compared to Anasazis?" - Review of Five Ten Jet 7 Climbing Shoe

My closest climbing friend has these Jet 7's and seems to be crushing two grades harder since he got them (he trains like a monkey on amphetamines too...) I've been climbing in Anasazis for 3 years and love them for everything but really steep bouldering. The v10's I've been climbing in on steep stuff are great for masochists, but just as I am starting to be able to take more than one burn at a time in them, the heel cup has started slipping off on hooks. How do the Jet 7's size compared to Anasazis? Should I go up, down, or take the middle path??
