Josh, We just ran West Fork on Saturday (hadn't run it since last season). It was running at 200cfs and we had a fun/carnage free run. It is continuous, steep and has a lot of quick-twitch read-and-run moves in it. I would say it's a half step up from SSV because of the continuous and contstrained rapids. If this is your first time, be sure to scout all major rapids. Particularly, be sure you scout Gun Shot rapid as it has some serious wood lodged just below the entrance (currently a mandatory portage). It comes up on you very quickly so have your portage eddie marked.
Anyone with a saw and rope who lives up that way would make some great friends in the boating community if they took an evening to clean it out (probably less than 2 hours work).
I am a weekend worrior so weekdays don't work for that run (ssv is my after work run).
Here are some great pics my buddy took from the weekend:
