I'm wondering the same. I have the sl00 but have no specs on it. Supposedly its got larger lift around 1200 lbs but i still question that.
I cant even find it listed on any branson site, but it's being pushed to the dealers cuz i have one LOL!
I was told it was between the 1200x and the bl00, for more of a "mid range" without the heavy price tag with the 1200x. It still does not have quick attachment tho. I'll be adding my own.
