Mine is plenty long for all of my hammocks except the WB RR bridge, that combo absolutely sucks. I have to add an extension that I bought with it, and never used except with that hammock. But the extension only seems to make the stand flexion worse, and I really do not get optimal results at all with that combo. When I want to test this hammock, I find some trees at least 15 ft apart!
Also, for some reason, my Speer hammock does not like the Vario stand. Not near as bad as the above, but not great. It's fine once I am in, but getting in and out is miserable. I have never figured out why, it's not a long hammock at all.
But all of my WBBB, all of my HHs ( way long and saggy Safari is tricky but doable ) and Claytor and JRB bridges work just fine. Just keep in mind that the uprights flex a lot, and you will always need to account for that one way or another. Isn't the ENO 10 ft long? I use my 10 ft Claytor with ease, and I have even used my 11 foot WL. But I would not recommend buying that stand if you plan on using it with a WB bridge!
For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us....that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God. For we know that the whole creation groans and suffers the pains of childbirth together until now.
