Hello, I am saving up for a doubles configuration and am purchasing my first steel tanks. A buddy of mine has offered some up to date LP 108's to me for a very good price ($300 for both) and I was wondering if these would be absolutely too big for a doubles rig. I am young and my back is in good health so I can take it but are there wings out there big enough? Help me out, what sort of lif capacity would I need for something like these? 55lbs? More? How do you calculate what is needed? I cannot imagine these tanks being that negative in the water.
Thanks for helping a newbie.
Can you tell us what you plan to do with the tanks in terms of your goals / where you are now? i have 2 friends that dive Lp108 on of them is 6'2" and built, he dives them ok the other one is a little smaller 5'10" he is fighting them on land like crazy. i see you live i Florida i do to, are you going to dive them in the ocean or in the springs/ caves? those really suck in the ocean for the most part, i have some LP 98 and im slowly getting sick of them. Also take into account that a drysuit is really recommended when using those LP beasts.
108's are great tanks from what i here but i think they're use only out weighs there size when you really are going to use them to where they are needed.
from how i see it
no deco dives to deco dives in the ~150-165 foot range can be done with double 80's. no drysuit needed on hot days or heavy lifting. Lifes great

ballaned rig so u can swim em up if your wing poops out.
deeper or longer deco dives in 150- the bottom. then yea the 108s would be useful and worth the hasslle. espeially since u can fill em a little over the rated pressure if you know what i mean
im not to sure about cave diving tho, as i know people that make 80's work great in caves. but know others that swear that LP steel is the only way to go in N.FL
if you have the 300 buy them as thats a great price for 2 tanks but keep in mind that the tanks are heavy as hell and give you a large amount of unneeded hassle in and out of the water aswell as extra gas that you could do with out if your a beginner in doubles/ tech.
if you do get them you will need a 50-60 lb wing, a drysuit and and aluminum back plate. plus lots of diving to get you, mr and miss left and right tank, and there buddy mr drysuit very very well acquainted
