Well, it sounds like you know everything, and aren't here to learn. I suggest trying
www.amsnow.com and leave this board to the people who want to learn how to make a Yamaha do everything they want!
I don't mean to sound like an ass, but if Yamaha sucks, there's a bazillion year old Yellow, Green, and Red sleds forsale used. Funny how most of those riders buy a new one every year or two, never tune them, and claim they are the shit.
How about riding in areas that don't see the traffic you are used to? If you want a rough ride, head for some bumps! I got to ride a Rev 800 last season, and while impressed, that thing would beat you up in the stutters too, every sled will.
Now to back up a bit, the SRX is a lake racer that can handle like it's on rails, at what point did you think it's a ditch banger, and when did that mean it sucks? The skids in the '00's and up transfer qutie well out of the hole, which is what it's meant to do. 3 foot moguls...try a long travel sled!
Now, I have ridden a few SRX's in washboard conditions, and found that I could push them just as hard as my long travel sled, no problem. I am in the middle of the weight specs that Yamaha tunes their springs for though, if you're 250lbs and up, then it's going to be hard to tune the skid for you.
I guess what I'm trying to say is, the sled can do what you want, if you're willing to tune it, tweak it, mod it, etc. No sled does everything, all have their strong points and weaknesses. Pick the one who's strengths fit you best, and try not to bitch.
