If anyone's curious, I've been using a 0.60 bass Elixir on my Suhr 7 for the last couple weeks. Works like a charm - I'd prefer more of a 62, I think, but it's a better match for a 10-42 set than a 68.
Obviously, this only works on double locking guitars.
For some reason, Elixirs cause me trouble in double-locking guitars. After un-locking and re-locking the nut a few times, they start to buzz against the first fret. Drew must be gentler with his nuts.
