I'll go ahead and put an order in for a 711... I don't have a lot of HEAVY chopping to do - I just like the reach of the bigger blades. But a sharp seven inch does come in handy when you never planned for it.
I chopped down some bamboo that was getting out of hand on my road and a few vines that were in the fruit trees. That's about all I do but I do it everytime I head out the back of the house.
If you want a GREAT 7", try the 711! Or break down and get a chopweiler. The all-time-best 7"-er there is. That's objectively speaking, by the way <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
