Euka - Spirocores are a great string for the reasons you mentioned in the first post. on the other hand, they are also a bit on the stiff side, and if you are having tendon problems for whatever reason they might not be the best string for you in light of this. Many people who love the sound of spiros but who don't care for the tension end up going with spirocore which gauge or even spiro solo strings as a good compromise. I start off all my jazz students by recommending spiro mites, and we usually start with them fairly low and gradually build un the string height to match their technique to make sure they don't get hurt. I wouldn't put spiros on a bass with no adjusters in general unless the bridge was perfectly set up by a luthier, and for a person with tendonitis to play such a bass seems like it could be risky. If you had a good setup with adjuster wheels, the spiros could still be fine because you could put them at a relatively "safe" height at first. As always, EEMMV.
Thanks. Tension is indeed a concern, especially since the bass doesn't exactly play like butter right now. I do need to educate myself on the properties of each kind of strings, but I guess the strings forum is right over the corner. In general, are nylon strings supposed to be low tension? It might just be that I like this bass' playability best only because of the strings.
An adjustable bridge is very likely a purchase I'll be making.
By the way, I've read that string height has a deep impact on volume, correct? So the compromise goes something like playability vs. volume?
