Biggest weight loss on your unicycle?

A friend of mine milled my moments. I gave him a picture of KcTheAcy’s milled cranks from this post.
He took out even more material, which makes me nervous.
I don’t care much if they break, especially with Moments being $50 now, but I don’t want to get hurt.

Looking at the picture makes me more worried than in real life. But they’re still pushing the limits more than I’d like.
What do you think?
