Can I Use Double Cylinders for Aqualung Pro LT

[Bent Benny]

My max so far has been 71ft but most of my dives have been 30-55.

should have at least an hour at 30-55...

If your profile is accurate you're a relatively new diver. Most new divers are heavy air users and don't get near their NDL before they run out of gas. While some folks will always use more air than others, especially a bigger guy compared to a petite woman, with time and practice you'll use less air. Lots of people don't get near NDLs on just one or 2 dives in a day, since depending on depth some of those times can be pretty long; it's not a requirement to hit them. Jumping to doubles and trying to do it with a less than ideal BC, or thinking about sidemount, simply because you want more bottom time on basic rec dives seems overcomplicating things. What size tanks are you using? Maybe what you should be looking into are larger tanks?

Some of the Zeagle line of back-inflate BCD's can take doubles (Ranger, Express Tech etc.) but not your Aqualung.

What they meant was contact your dealer so they can sell you something that can - most AquaLung dealers can get Apeks gear and they make bp/w configurations.

I'm using Al80 tanks. Getting alot of great feedback here thanks alot everyone.

rent, beg, borrow, steal or buy some steel 100's......you'll have them for life.

HP tanks lend themselves nicely in cold water configurations. Personally I like LP85's because you can get great fills on them and HP120's, both trim nicely, 100's in doubles don't trim well most of the time. And when you grow into doubles they double up nicely. Like Jay said tho, 100 singles are pretty sweet for NDL diving.

If you double up AL80s's they're going to be really buoyant near the end of the dive as they get empty.

My instructor/owner of my LDS told me not to mess with steel tanks. Why do you recommend them? He didn't give me much reason other than they can corrode and rust easier than and AL tank.

Gas contained in double AL80s doesn't weigh any less than gas in steels. You will need more lead elsewhere if you're diving aluminum tanks in order to compensate for the initial difference in buoyancy though.
