I thought I'd share my experiences putting together a travel rig for AP using the Skywatcher Star Adventurer mount in case anyone else has had similar thoughts.
I've done a little blog post so I won't reproduce it all here, you can find it, with images, here:

TLDR: It works well if balanced properly and PA is good. Guiding worked reasonably well but isn't absolutely necessary for short exposures. I guess the proof is in the images and while I certainly won't be getting rid of my proper setup I'm pretty happy with the results - especially considering I can carry the whole setup easily by myself, it all fits in the boot of my tiny car, and it doesn't require mains power or a big battery to run.
The WO Star71 is a great little scope and I'm looking forward to doing some widefield narrowband with it using my STT8300 on the EQ6.
Also the A7s is a bit of a surprise being reasonably sensitive to Ha straight out of the box
