Not really a big difference.
I feel a subtle difference in weight, they just feel lighter when I grab them.
Adjusting the clutch lever is great. 6 positions to move the friction zone around on the lever action. You can set it far out, or closer in. Wish I had that on MSF day....
I also had to slide my hand down just about 1/4 to 1/2 inch on the grip to allow for the first large bend in the lever and my pointer finger. Pointer finger would ride up the bend in the lever. Messed with my 2 finger braking. This is my first set of adjustable levers, hopefully I can adjust them to get my hand grip placement back.
WARNING! Be careful with those lever bolts. They have very soft threads and you don't want one ending up like this when you try to put it back together. Ask me how I know.
[Edit]
I mainly did this mod for moving the friction zone closer on the clutch and looks.
