1077xl vs 2027x vs 8527
Search the forum for more info on those guitars (richly available in the 7-string section) . They are all very fine axes, it all depends on personal preference.
It's too bad you cannot try those guitars before you buy, because that's the only way you can determine which axe suits you best.
If you want to get rid of the muddiness you encounter on "other" seven strings, I suggest you try the RG1077XL. The 27" scale of this guitar provides higher string tension in very low tunings "so everything stays nice, tight and clear".
For most people, the longer scale doesn't cause any problems regarding stretching of fingers, etc. But then again, it all depends on how YOU feel with it.
You say you don't need a piezo output, so I don't think the 2027 will be of use for you. (Although a very very fine axe)
The 2027 has a "normal" ( 25.5" ) scale length, that's the same as a "normal" seven string, and thus wouldn't cope as much as the 1077 with the floppy strings.
Just my humble opinion.
Oh, and btw, welcome to the jemsite forum !
