Well, lemme tell ya, I have a WL Tadpole, when I was hanging in a big ole 11' gathered end job, I always felt the coverage might not be enough, using the popular formulas for a ridgeline length. So I have always thought about the need to replace it. Through all my research, I have decided on the Superfly. However, now that I am hanging in the WBBB with its fixed 100" ridgleine I feel like the tadpole is PLENTY big enough. I get almost 16" of coverage on each end now. I have not been in any harsh weather with this set up yet but I am very optimistic. I may still end up replacing my Tadpole, but it is gonna be for the brown, only because I don't care for the green over my multicam WBBB.
I am not a super cold weather camper, I live in Louisiana. So keep the Tadpole in mind for your ENO as it is a shorter hammock.
