Can I ask why you are against using an adapter
My guess is that 95% of the tapers here
use and adapter of some sort.
The rapid adapter + a thread adapter into a t-bar is easy to set up/take down. It's feild tested and is essentially
one piece, meaning you can undo the rapid adapter and throw the whole top of the stand
in the bag with two twists of a wing nut.
It sure beats the round and round of will this work with this jive.Bottom line is that two different people have ordered the same bar and gotten two different things.
So drop the extra $15 and get it done.
