Well some kind person once gave me some loop 75s? and I thought I'd try one on my peg bridge Buchanan mandocello (there's not room for both) - but the crimp might work on a very fine string. I'm going to have a go at a fully-octave tuned m/cello, which will go from 60-something (the 70-something will almost certainly be unplayable) on the low C to a 9 or less for the high A. I very much doubt it'll work though (I'll certainly need to hide the high string behind the low octave, or it'll snap upon striking.
