I guess it might offer greater flexibility if visibility is mainly poor but occasionally opens up. Perhaps you should consider an 80 or 90cm gun?
That's pretty much it.
Sometimes in thick weed or around murk and structure and other times it opens up and is deeper / wide-open.
I want the best of both worlds. I'm looking for a reverse trigger mech to give me the power / range of a strong 80, but the maneuverability and compact nature of a 70.
