Do any of you have suggestions on strings that are easy on the fingers? I usually play an upright big band gig about once per month and I really don't practice more than once a week on upright. Therefore, I'm usually hurting after a 3-4 hour gig. I currenly play Spirocores and I love the sound but unless I can find more time to play upright, I'll always have problems with blisters, etc. Are strings such as the Velvet Garbos easier or harder on the fingers? Are there non-gut strings that may suit me better than the Spirocores? Thanks for whatever info you can provide.
