In general, non-flying shore jobs < flying shore jobs, at least as far as staying on the DH-XO-CO-MAJCOM-Flag track. Personally, I say persue interesting and rewarding tours, rather than mindlessly trying to stay on the Golden Path (not to say the standard career track can't be interesting and rewarding, just that I've known lots of guys who value the 'right' billets uber alles and will tell you to disdain anything else). If an intel track is interesting to you when you get to that decsion point in your career, go for it, just be aware you may be going down a rabbit hole.
And to echo MB, don't bring it up with Millington or your first squadron chain until you're at the no-shit, I-need-my-next-orders point. Some skippers will interpret you going for nonflying gigs as volunteerring to take yourself off the career track, and will use you as cannon fodder accordingly come fitrep ranking time. As Jimmy Buffett said, burn that bridge when you come to it.
