I've been playing BG for about half of my life, the last five of which have been somewhat serious. I mainly play jazz, but I also listen to hard rock/metal, funk, and hip-hop. I played upright for about a year a while ago, but due to life situations I had to sell it. Now I'm in a place where I can afford a upright, but my living situation doesn't allow for an acoustic one, so I ordered a 4-string NS Design NXTa. The instrument itself is on backorder for a few more weeks, and I'm thinking about changing the order to a 5-string. I've read that the low B string speaks a lot better on an electric upright than on many acoustics, and the idea of bowing a low B or playing a cello part a full octave lower is pretty cool. It would also let me stay towards the middle of the neck instead of the lower positions (at least, that's how it works on 5-string BGs). I have read that it makes bowing harder, though (or at least, you have to be more accurate with your bow hand). Are there any other downsides to the 5er? Do you feel that it's worth having the extended range for the kind of music I play/listen to?
