You’d be amazed how good big trail/enduro/all mountain bikes are these days tbh. And the bottom line is, there’s hardly anything that can’t be done on a good, normal bike- and the stuff that can’t be, well, you’ll probably not be doing it anyway as it is properly mental. But a sensibly specced 150/160mm bike is up for pretty much anything. Not as fast as a full dh bike but still.
For jumping and the like, a dh bike is brilliant at landing but they’re not that good at taking off- hefty, less agile, but also all the human input of weight movement etc ends up fighting against 8 inches of suspension.
But like I say- a full dh bike fundamentally sucks balls at anything that isn’t being a dh bike. You’ve got some really good uplift venues down there but is that really all your mountain biking will be? Not that likely.
