WBBB Hamock - Hammock Gear or WB UQ?

[Copenhagen69]

I have not seen a WB Lynx winter version in person. My buddy has a HG Incubator 20 with 4oz overfill.

It brings me to 2 questions ...

1) Is there a different type of fit between the 2? Will the Lynx full length work better with my WB or will it not even matter?

2) I think the HG is a tad older version, but if I could trade a knife for the HG or sell knife and pick up a new Lynx? What would be the best bet as far as best overall performance?

EDIT: Not yeti, I meant Lynx full length my bad ... fixed in post
