I've not had a chance to swap my VH II and RY around yet, and to be honest I think the RY is going to be too strong in the upper mids for that guitar, but back to the topic of the VH II in an Eclipse; the thing about the Eclipse is its lack of resonance. They're great guitars to play (I have three of them) but even though they have a set neck construction with a mahogany / maple body and mahogany neck they are very dry, when compared to a Les Paul for example, which presents some problems when choosing pickups for them. My experience is that unless you are a very technical and disciplined player (which I'm not - I started out as a bass player!) then a slightly compressed pickup is going to be high on your list of desirable characteristics (the guitar's lack of resonance doesn't smooth out differences in playing dynamics in the way that a much more resonant guitar would). I've tried a few different pickups in my Eclipses and my favourites so far are Rebel Yells, Crawler (bridge) and an EMG 57/66 set. The most disappointing was the Alnico Nailbomb set (mainly because the bridge was so sensitive to dynamics which was really emphasised in the Eclipse) but they sound awesome in my Telecaster HH (again, mahogany set-neck with a mahogany/maple body but much, much more resonant). Personally I'm tempted to try a set of Cold Sweats next.
I hope I haven't rambled on too much and that some of that is useful to you.
