Them NS Uprights look great, I love that there's so much neck, one thing I hate about my EUB is the short neck, I can't stand playing in thumb position.
I wonder could the 5er's be bowed easily...
I've got an NS CR5M, love the thing to pieces. It bows VERY well...can't comment on the NSX's as I've never played one, but my guess - based on photos - is that it will bow just fine.
