I got round to listening to those at last. Thanks Dave and nice playing.
The main thing was, for me at least, they all sounded wholly acceptable. By which I mean I could have used and worked with strings that sounded like that. Having said that I liked the La Bella and the GHS most, strings which I have regularly used, along with the DRs which I am using on one bass at present. There's something about the EBs and the D'Addarios I like less (but I bet I could not spot it in a blind test).
But, never mind the sound, all those strings feel different under the fingers. For example, the DRs are slightly rough to the touch while La Bella 760M are very smooth. Tension and compliance vary a lot so, even having heard the sound, I think you can only finally decide after playing them.
By the way, GHS don't, as far as I can see, do a 50-105 set. Should it be 45-105 or 55-105?
