I just strung my J bass up with some TI's after having some Kalium strings on it for a while. Oddly enough the TI's feel stiffer than the Kalium strings. The sound improvement for my personal tastes is huge. As much as I liked the feel of the Kalium strings, I just can't stand the tone they gave my J bass. I might try them on my Ric though. I had put off buying the TI's for a long time because of the cost, but my wonderful wife bought me a set for Xmas. It feels good to be back in the TI fold!
