Congrats on the long arm!
I think this would be real fun swap, but I'm another that is not in a good situation to participate in a swap. Currently have the house far sale so don't want any commitments.
With your long arm, one thing to consider is floating the top instead of rolling it on the front. Once I started floating my tops, the whole process got way simpler. I have a cord with sliding clips I use to keep the top square as I advance the quilt.
