I've used both a SW 130p and SW Startravel 120 on the AZ5 and found it incredibly easy to use and my equipment feels secure. Particularly the 130, which feels almost toy like on the mount.
There is a touch of focus wobbles but that's mostly attributed to the light weight tripod.
I do feel the AZ5 would benefit from larger alt-az clutch knobs. They're not always easy to find in the dark and until I got used to the mount, did on a couple of occasions accidently unscrew the extension tube nuts whilst fumbling!
The slomo cables were tried once, but they felt a bit pointless using short tubed scopes so were replaced with the original knobs.
The heavy duty 1.75" tripod does improve stability and increases the AZ5 mount load capacity to 9kg.

There's also a cheaper Astrotrac aluminium tripod with 3/8s adapter available from 365Astronomy however I can't comment on its performance.
