Re: Wizard I and string guage worries..
Well... I changed the strings to 10-52's. They work for me. The low E sring is a little floppy with drop C. It's fine at D tuning. E tuning would be pretty tight. I can go from D to Drop C without having to re-setup up the guitar and the trem is operational (not blocked). As a matter of fact I can switch to Drop C using only the fine tuners.
With the 10-56's I had to screw the trem claw about as far as it would go. I also had to put my 3 trem springs in an arrow pattern.
For the 10-52's I left the springs in an arrow pattern and was able to back off the claw screws.
My feeling is if you don't have to add a spring, your probably ok. Think about it.
I would never try to tune those 10-56's to E. That would be pretty brutal, and you would definately nedd to add a spring. I know you blocked your trem, but still..
Overall the 10-52's seem better suited to the guitar. Like I said before, the 10-56's, particularly the 56, seemed out of place. Though, there are people on this board running that and more for there low E.
If I were you, I'd think about a tremel-no.
And Yeah, I bet those 10-46's were kinda floppy in D.
