1st metric or other is fine with me also.

2nd, Explosive bolts,  I wouldn't use them, though I don't know much about
them.  Wouldn't they probably have to be replaced frequently to maintain
reliability, especially in a high pressure salt water environment?  Also I
believe one would have to obtain a Federal license (at least in the States) to
purchase them -->big pain:(
