Done a complete eyelet swap, just haven't ever had it requested on a new set. It may be costly, but sounds like it's the way to go.
I do have a question, though. Typically, whenever I would see a CCM eyelet fail, it would get corroded then start chunking off. However, here's my question - how is it getting to the point that it's stretching the eyerow? Does he like an extra-tight skate? Is it a situation that the eyelet condition isn't paid attention to and he continues to use them after they've broken?
Perhaps try lacing outside-in? Different laces? It just seems that it is stressing the boot quite a bit.
