Thanks for the attention here
Dogwood: 13 oz sounds very, very tempting !! I do know of TT, SMD and GG, but it's got to be something closeable for winter, I'm not 20 anymore

I love my Gatewood, but look for a slightly bigger, more stable and well vented winter-convertable option.
And yes FamilyGuy, maybe the Utopia 2 is an option, or the SHANGRI-LA 3 (the old Hex 2) or why not one from these manufactures linked here ?
Just heard of a swedish woman planning to stay all winter in Svalbard in a Venor Lavvu
