I don't really agree with that assessment because if you are digigng in hard then you aren't really worrying about dynamics. Any string is going to give better dynamics with a light touch. The string can only do so much to induce a signal in the pickup. After you get near that point all of the bashing and thrashing is just wearing out your fingers. TI's aren't magic in this regard, but the lower tension means that the usable range is reached sooner. I beat the snot out of the TI Jazz Flats on my P bass, and they keep on ticking. You will know if you killed them because the intonation will start to fall apart. It took a huge amount of playing to make this happen, but it did happen. Otherwise they are just a great sounding string. I'm pretty much down to using either Jazz Flats or Super Alloy. I've used a lot of powerbass and jazz round sets and they are excellent but i like the superalloys the best out of all of them.
