Hi,
Naish seems to have two different inflatable constructions: a fusion dual-layer construction and a LT Construction. Is one more premium than the other and the other a more economical option?
Going by this video it says....
"We offer them in a fusion dual-layer construction which is basically the equivalent of a full sandwich composite board. Meaning that you have a two-layer structure which makes the board very, very resistant.They're very, very durable and they keep their shape, unlike other lower quality brands. Our LT construction is comparable to what you would have in a hard board, also known as a composite board, that has a PVC or a wood stringer. You're looking at a single layer skin where a stringer is fused on the board in the center line of the board. That gives you slightly lighter weight in a great package. "
Have a look at the Red Paddle boards, extremely durable and stiff. Pump up to 20 psi which regardless of what they said in the video equates to better stiffness...
The fusion dual layer will be more premium and expensive than the single layer LT construction I'd expect.
The fusion layer technology is also lighter, due to the saving on the glue weight, and may minimize the risk of having a defective board due to gluing issues.
Gong(*) produces the same shapes in both technologies, and for instance on a 10':

With fusion: gongsupshop.com/epages/box1707.sf/fr_FR/?ObjectPath=/Shops/box1707/Products/GON7SUPCM10
The glued one weights 10.5kg and the fusion one 9.2kg, even with its added equipment (handles, luggage net). Not really important in the water, but really noticeable by kids & women on land... but the fusion one is is 44% more expensive.
