Don't be to hasty say now you don't need a ratmandu, it is a completely different creature and as much as I love my res-c, the grip on the rmd might be one of the most comfortable I have ever held. If you get the chance to handle one you will see what I mean.
I used to have an RMD...couldn't warm up to it.
I'm hoping I like the Rodent 5 though <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
