I looked through my shims today to give my 1000 a bit more lift (it was super light) with my 255-2/115+ and didn't see a +0.5. Looked at an online shop and the standard six shim kit doesn't seem to have one either. Does one exist? I see that there is a -0.5.
The 1.0 was like riding an elevator even in 10 kts - I don't need that much. Came in and swapped back to the 0.
I have an old 255 which I can use with a -1.5 I guess?
