Thanks Gav, thats good advice. you're right there is not much left in the adjustment screws and I cant get longer screws as they are already too close to the pickup for my liking anyway. I would actually much prefer not to use the PBG screws given how close they are but that would require a big shift in bridge position.

I've ordered a custom colour from DB, rosewood (or as close as possible). I was going to drill and position everything while I was waiting for the "mad scientist" to work his magic, after what you said Gav, I am thinking maybe I should wait, stain it and see how visible the plugs are at that time. If they are visible, I drop the bridge back, if they aren't I'll just remeasure and position the bridge.
