Did you switch from the air UM to the Valk 3 because of the sponsorship? Or do you just prefer the Valk 3?
I went from UM to SM for a bit, but then switched to the Valk 3. I was trying it out after the sponsorship, and noticed that I can get the same times on it, so why not use it. I also ended up breaking all my PBs on the valk.
