I have a 3, 7, & a 10. I use the 3 for general rifle work like inletting and carving. I use the 7 & 10 for engraving, I use the 10 more than the 7 but I use both. My wife does beading and she uses my 10 a good bit to do that. I don't mind the band and I can flip them up out of the way if I don't need them.
