The TRS all the way. The T.Rice might be too firm, and the BM is overkill.
What do you mean the Magic is overkill? In which way? Considering that the difference is only $100, I am kind of tempted by the proper sintered base and the basalt/non-fiberglass construction... According to the Mervin guys it is also supposed to be quite a bit better in powder, which is important to me.
