The Mules were OK if a little tame; the tone was very neutral and the volume was hot enough to drive the amp with a little bit of grit in the low end but they didn't quite have enough bite in the upper mids to stand out. On low gain they are very mellow rather than jangly which suits the neck better than the bridge, and on high gain you can get Steve Steven's tone from "White Wedding" quite easily. So basically, nothing wrong with them at all - a bit of a "jack of all trades" really.
The Crawler bridge in the Eclipse is great for 80's rock and pop; driven hard with some chorus it covers most new wave bases very convincingly, take the chorus off and turn the gain down a little and you've got a more traditional rock tone, and take the gain down further and split the coils and you've got a very convincing single coil tone.
The Rebel Yells in the Eclipse took some tweaking (they are notoriously height sensitive) but once the sweet spot was found I real liked them; they really roar when driven hard but also have the presence that the Mules lack when the gain is turned down, however they're not as convincing as the Mules when it comes to a more vintage tone.
The Nailbombs, for whatever reason, didn't seem to work in the Eclipse; they worked perfectly well in other guitars but the chemistry just didn't work between NBs and the Eclipse - reflecting on it I think the NB needs a more resonant guitar.
I haven't tried the VH IIs yet in the Eclipse but from using them in my Showmaster and knowing how other pickups behave in the two respective guitars, I'd expect the VH II to have too much low end and not enough presence to shine in bridge position of the Eclipse, however, I'd expect the neck pickup to be ideal for clear, articulate leads.
