I strung the Fender with a set of Thomastek-Infeld strings. Yes, on the pricey end but yes, definitely worth the cost. These strings feel great and ring out nicely. I’m not sold on the balance of the gauges (the D string sounds a little bit louder than the other three). I might have to experiment and buy a few singles but good stings.
I don't know about T-I banjo strings, but their mandolin strings are very good, quite durable, and distinctively different from any others I've played. In the neighborhood of 10 times the price I usually pay for a set, but they're a bargain compared to T-I's similarly-made Precision violin strings, which go for only a few dollars less-- and you only get half as many strings. That's their cheapest line of fiddle strings-- the top-shelf ones will set you back over $100 for four little strings. ....Ask a classical bassist some time what strings cost!
