I did rotate the second set, and pushed the Angle End to 100, that last was not the most flattering, but it demonstrated the problem better. I still don't think that 8 is enough, but I hope I'm proved wrong. 18 is a lot so perhaps there is a happy median. Any way for the moment I plan to push on with 18 light set and try to make the ERC a bit more user friendly before I put it up in the freebies.
