On the suspension note,
I found a full susser really easy to jump badly
Try a fully rigid for learning the technique, I learn’t on a trailstar with Z1 with the lockdown to about 25mm of very stiff travel.
Then go back to suspension which in some ways is now harder work, as it feels energy sapping, but equaly seems more rewarding when you get it right as you go for miles!
Practice Practice Practice though, its definately a summer technique as turning up at the dirtjumps to ride in this weather is a sure fire way to not be welcome back in the summer. Take a spade and make some friends.
