Mike on the subject of Magnex's, Harvey said when fitting the 6degree beam some magnex's hit and other don't. I know yours did, but how old was your magnex? I know mine I bought from you was one of the newer batches with the smaller tail pipe so wondered if that may have been different? ie whether it was just completely random that they hit or whether it was a when it was made was the difference?

I guess I'll find out soon enough
