Ooh, seeing the rod gives me a better understanding on how it's used, thanks.
I have to buy a stop for general rail use (like start and stop grooves instead of a full pass) so I wanted a second. The one that came with my TS75 is good but the one that came on my MFT/3 is even better (if it can be used on a regular rail). I'd also use it as a second for my MFT/3.
