I have no experience with that style of hack, I use the longer shank braided nose. But from what I know about those, I would say I'd bring the nose strap up just a touch. The chin looks good, just make sure you can get at least two fingers in it when it's relaxed. I found with Hoover, once he got used to the hack, he barely needed the curb...it was basically just there to keep it on. I could get four fingers in it when I tacked him up...he was going off the nose pressure to halt.
