Hi Everyone, i am new to the site and haven't been able to see any older posts addressing this situation.
as a cold water BM drysuit diver, i carried a HP100 and slung an al40 as a redundant air supply. after 45min to 60 min dives at max depth 100'+ i would regularly surface after safety stops with 1000+ psi or 34 cubic feet of air still in my steel.
now i have switched to sidemount (SMS75) and am not sure what tanks i should be using for recreational diving. i've been playing with 2 x al40's, 2 x lp45's ...(ya i know..funny) but there is not enough air for redundancy. 2 x hp100's are over kill for recreational diving, and al80's are just too light to be used with my cold water gear.
unfortunately there are no dive shops around here that rent or have different size tanks to try aside from al80's.
using the rule of thirds, i figure i need 165ft3 of air for 2 x dives + an additional buffer for extra air. it seems that my options are something like HP80's, or lp85's. i haven't dove with either of these tanks and dont have the ability ot see what they would be like in the water without ordering them in from my lds.
anyone else in the same situation that has found a solution?
Thanks
