| Hi. I tell most people not to buy 7s. And that comes from someone who had two sets of 7s, did DIR F in them - and got rid of them both to dive 12s.
However - if Chesil Cove were my local site and I was regularly diving in that range - and diving Chesil Beach at that - I'd stick with 7s. 12s on the Cove are too much hassle to be honest.
I'm not too keen on the "take a stage for deeper dives" approach though I must admit. Twin 7s give you reasonable gas reserves up to the mid 20s. Beyond that 12s are a better bet. It's a shame that we can't use the same kit for all our diving - I think that every time I look at 15s or 18s in my shed. We just have to tailor our kit to the diving we do the most.
