Bottom line is I am getting one of these jewels -- the newer RM3Di -- for myself, and I will be happy to push it to the limits for testing when I get mine. I remain comfortable that LCC will handle the extra 2.5mm of shift, since it handled 25mm of rise.
Any way we want to slice it, I am comfortable stating that worst case on the 43 is you'll get at minimum 80% of the full IC on it with the IQ180 using the Tech-Wide LCC in C1. And in cases where corners are not critical, we'll probably get comfortably more.
And I *may* get my hands on a 40 HR-W later this week to test, and if so I will add that data to this thread.
