To Nick and Padowan thanks.

Nick i have pm'd you for spread sheet.

will have a look at calc's and try to work out whats best to take.

Ideally i want to start first dives with 230 bar diluent

so i should only use 70-80 bar dil max (unless i have to do a dil flush!!)

so will be topping off from around 150-160 bar ish
