I hate to say it, but it sounds like all you need is practice packing. Psycho packing is something people do that I find really fussy. You can do whatever you want with a pro pack if you learn about it. But, to be honest, the only thing you need to do is clear lines from fabric, keep the lines tight and keep everything together when you put it in the bag. I found psycho packing the easier solution to keeping everything together when I thought packing was hard. Now I've had a bit more practice and I propack everything.
Seeing as your initial problem related to a canopy too big for the d-bag and keeping control of it when you put it in the bag, find someone who packs for a living, pay them for a pack job and then see how they put it in the bag. Better still, talk to someone who packs for a living and see how they pack canopies that are too big. You never know, you might get some useful pointers. Good luck.
BTW, what is a wolmari pack? I've never heard of it.
