Thanks for the perspective guys.  Being a new MODO users, I was just wondering what advantages this might have for a proficient MODO user and whether it would add to my capabilities or be redundant?  If its simply more tools to learn, then a fatter toobox just adds to my challenges.  OTOH, if it does something different or better, then that would be a reason to take on a bigger challenge.

I started out with Hex (never got a handle on it), then Cararra (OK, but clunky interface) and then MODO which seems the smoothest and easiest for me.  Dan Ablan's video tutorials really help me the most I think.
