Which TWINS

[Kevin B]

Trying to weigh up the pros and cons of twin 232b 12s vs 300b 10s. I expect this has probably been debated before (many times) but would appreciate any views espicially wieght considerations and are 300b fills widely available and do you get a good fill.

thanks

Great title for a post, with the contents a real anticlimax.

232 12s will be the almost universal answer. It has been debated many times and is one of the few things most people here agree on.

You're right about the fills issue, but in addition to this you have in-water trim and on-boat comfort with 232 12s.

Unless you are about 4'10" - 10's are too short, so go for 12's

Pros
more gas
less weigh on weigh belt
most places always got a good fill

Cons
heavy onshore and lifting onto boat
need 300bar din fittings
Need 300bar crackbottle in your smb or cant fill from them

This is what i found with mine, but i sold them for twin 2's

As the previous poster said, don't bother with the 300-bar 10s - unless you're particularly short, they're awkward to wear when you're sat on the boat, they don't trim as well as 12s and getting a 300-bar fill can be a pain in the arse. My advice would be to go for a set of twin 12 Euro cylinders with a decent manifold and a set of chunky cylinder bands.

The absolute best twinsets you can buy at the moment are these... Halcyon UK

They are quite pricey - £420 - but are the absolute dog's nads, as far as I'm concerned

I thought this was a common misconception due to the weird way gas acts under pressure. Nigel Hewitt has some interesting things to say on the matter.

usually you get 310 bar fill, cools to 290, lowers to 280ish hitting water, i still got more that the 220bar i end up with in my 232 fills

Height and strength are two factors when this debate comes up, I used to have twin 15s but Im 6ft 6 and 23st, can could handle the weight, I however tried 300b 10's and for me they felt very awkward, but twin 12's are more common but its down to how you feel, Id dive both and make the decision afterwards?

i have Faber 232's with a holycon 300 bar manifold. sweet. until last week i took them into a certain Glasgow based dive shop. they filled them up to 350bar. nearly shat myself. just as well they were up for test.

That could have been a nasty bang , might be no harm for the staff in that place to get a tip to check the info on the neck of the cylinder and notice the valves being 300 DIN treads.
