Foilpumping Pumpfoiling beginner's gear question

Might be the wrong forum, but my search hasn't given me any results whatsoever in the forums.
Looking for ways to expand time on water and improve general fitness as well as foiling skills, I want to start foilpumping on calm days.
I've been told learning will be slow and frustrating in the beginning, but I'm prepared for this.
My AFS Windfoil is probably much too small and seems not to be suitable for an upgrade to a big front wing, plus it's a Deep Tuttle design rather than a double US one.

What is an affordable wing suited for a pumping beginner of around 85 kilogramms?

Boardwise anything small and light seems to work, so I think I would go for a low-budget plywood DIY. Am I too naive here?

Have I overlooked threads on the issue in other forums? Then of course I'd be happy to find them.

Cheers,
Sven

Thanks, AP!
I'll try this.
