my apologies, i cant suss the multi-quote:
Correct. How much further back from the 25.5" line depends on the string - its gauge, tension/pitch, construction and to a lesser extent the action of that string.
for me, it would be 9s and standard tuning, but never say never, and i might sell it one day, and they may have different plans
There's no guarantee the bridge can be positioned appropriately if you line it up based on the pre-drilled string-thru holes, so be prepared to redrill them or at least 'massage' the alignment between the holes in the bridge plate and the holes in the body.
Yeah that was my thought process too, i have two bridges available for use, the hipshot mentioned, and an ibanez bridge. The position of the string through holes in the base plate, and the max and min of the saddles is different, so i may have to slot the holes in the body a little, shouldnt be an issue though i dont think.
