Eeehhh....??????????? Go on Thomas, tell us why on earth
we should use an ALU plate instead of the SS we are using.

I am diving with Øystein in Norway, and sometimes we have
a thing called "waves" over here.....with steel doubles, dual
stages and a cannister light, enough lead screwed into the
plate, lots of underwear and a drysuit, i fail to see what an
ALU plate would do for us..........And your choice in light
seems odd too. I want the 14 so i can use it as ditchable weight.
The 6 is probably a nice light in tropical conditions, but up here
a 14 seems like a better deal.
