Yep, and at risk of getting flamed, owning sr77 and INFI I'd say the only real world difference is how they corrode. If you don't mind carrying a care kit then sr77 will be your best friend. It's cost effective and tough, INFI will work best in nasty environments though.

Out in the wilds I'd have my S6 and my SS4 (or possibly Badger instead of them when it arrives) and in extreme areas a chopper; most likely my Tram bolo..

It's great to have options!
