Hi DJluc.
Judging by the mere numbers here, I would opt for the 122-liter model. It has been said earlier, that one should select a Futura of one size smaller than "normally" in terms of volume due to the new shape. Or more specifically, the added width. The Futuras can carry a wide range of sails, so I don't see your Carve sail quiver causing a problem either.
Hope this helped.
