I have to say I like the falling block better than the break open actions, tough I have some Handis and make no excuses for that. I like some features of each type of action.
It should be noted that this discussion has by and large lumped all the break open guns with the NEF. To be fair, there have been some excellent break open actions made that make the Handi look like a low dollar, walk around the woods, go-bang gun. Oh wait, that's what they are. That's what they are meant to do. Point being, there are some greater and lesser examples of both the break open and falling breach type actions.
Maybe some compay somewhere is going to come out with a line of "entry level" price point low walls. Who knows. If they do I'll tell you this: they will be thoroughly discusses, debated and contemplated here on the Graybeard Forum. I hope it happens.
