I just might do that. I'd be willing to have a 34" 5-string if the B string was usable. Like light strings, but I could always just get a thicker B while keeping the rest light or something. I just haven't been able to find many 5-strings in my price range that were 34" scale at the time I was out buying one.
I do use proper technique (or at least I think so). I only press down as far as I have to, wrist as straight as possible (strap higher because of that), but it still comes down to trying to do a 1-2-3-4 hand placement. I just can't comfortably reach that far. For example, playing YYZ is a lot harder on my 35" 5-er. On that song I'm lucky I can move up to a higher position and make use of that B string, but sometimes you can't, like having lines that are relatively easy near the 1st position, but have a quick part or something (say Aces High for example). I can move up to play the quick part easier, but I'd have to zoom right back down the neck to stay in time.
Why zoom down the neck when you have the notes available elsewhere? Keep in mind, anything you play in F or A# can easily be played from the 6th position.
