Thanks for the start Brion, I had an awful feeling no-one was going to reply, what with all the spam and such.
Anyway the upper band lands on a shoulder just as wide as the band, so I assume extra fasteners here would help. This band takes the forestay and one set of shrouds.
The lower band with bolt and now a sizeable hole for the bolt takes the running backstays and the inner forestay as well as the tackle for the gaff .This fitting is 2-3 mm loose so I assume I can pack this with epoxy as well,

Drilling the hole through the mast and avoiding the conduit was a nightmare, and I have to do it all again for the throat crane, any tips here?

Thanks for your help,
Glynn
