I'm VERY interested in the varied experiences with TX1's. I've heard so many people talk about how tame it is. I have not seen that at all. In fact, I think it's the most angular piece in the Motiv arsenal to date. There are some patterns where it will rival the total hook of anything in my bag. It is so angular that I gave one away and redrilled the other.
While on the topic, I drilled one with the pin under the thumb and dulled it to 500 grit and it was AWESOME on the nationals pattern in practice.
