I'm currently using a voltric 70 but am starting to find that the shaft is a bit more flexible than I'd like it to be. I can't find any reviews on the voltric 50 since it is relatively new and isn't very popular. If anyone had an opportunity to play with one, I would like to know how it feels compared to a voltric 70. I'm also curious as to how thick the frame is since I can't really tell from the pictures I found online.
