Is 12-56 too heavy for D standard on 25.5 inches? What would the equivalent in E standard be? I'm looking to beef up the strings on my guitar that I use for anything from D to B standard, which is a pretty wide range, but I'm using 10-52 right now and it gets pretty floppy for riffing on the low strings when going down to C and B standard. I'd like to use a wound G string as well, does that add to the tension?
