I have the EZ-up installed on a lowered 08 SEUC. It's probably the easiest of all the center stands I've dealt with -- about 1/2 weight lifts it. But... if you're a really aggressive rider, you will encounter clearance issues. It doesn't seem to really limit the lean angles, but when you do touch down, it hits a lot harder than the routine floorboard scrape. Both a friend of mine and I have almost lost it when we levered the rear wheel off the road by hitting little humps mid corner.
I've kept mine on for the convenience and just don't get too aggressive when riding two-up.
FWIW, I bought mine at the NE multi-state rally. The dealer had several center stands that were removed from other bikes -- both HD and other vendors. The EZ-up system looks to have the most rugged attachment system by far. There's no adjustment on the leg length, so if you want the rear tire off the pavement, just put a piece of 3/4 inch plywood under the stand. Makes it a bit harder to get up, but still manageable for a 150 lb. person.
