Yep - the Eldorado tie-outs don't match up with the Nest tie-outs, but it still worked fine in the ~50F temps I tested down to. I don't usually stake out my HH anymore so I don't think the tie-outs are necessary, but it would be a simple mod to add tabs to the Nest and Blackbird if you wanted to.

Agree with Pan - JRBs work on Warbonnets.
