if you really want to go the low-profile/single point route many people have had much success with the sony ecm-717 and/or ecm-719. they are basically the same mic, just a newer model. mine runs fine off of plug in power on my r-09 and md.
d8 vs. jb3 is a push, you have to transfer the dat, but you may run into weird interference issues w/ the jb3, which i've never seen w/ a d8.
just my $.02
