Ball & socket shround attachments

[conachair]

I'm slowly preparing my Ebbtide 33 for long distance cruising. At the moment the shrouds terminate at the mast into a swaged ball which fits into a socket in the mast. Now, these don't look up to the job to my eye, is there any data suggesting that tangs bolted through the mast would be stronger? I'll be replacing all the rigging anyway (possibly dyform and stalok or norseman terminals), presumably it's not too major a job to replace the ball & sockets with the mast down, anything I sould look out for if I go this route.

Many thanks
