Just 2 cents from the newb....STB222 I know where you are coming from...keep riding it you'll be amazed how 'fast' the twisty sections can become. I first started riding six mile this past winter, and at first, having not been on a bike much since my childhood days of racing BMX (35 now), I disliked the twisty sections for the same reasons you mentioned.
It seemed liek every time I got some speed up there for it to start to get fun, there was a sharp turn that made you scrub all the speed off. Recently have been riding a lot more, gotten to know the trail a bit, gotten to know the buike a bit, skills improving and have chased some really fast people through there. WHAT A BLAST!!!!! I cant believe speeds I can maintain now as compared to a few months ago, and how well it flows.
I guess I am saying that I can identify with your initial comment but these fast guys are right....twisty does not mean slow, it just means FUN!!😀
