The goal is still staying stacked, keeping the rear leg in control, and letting the barrel work from behind you. The mini can help, but yeah, for true low-away work a fungo is usually better because it gives you more room to feel the barrel stay long and work through that quadrant without feeling like you have to cheat it with your arms with that shorter barrel. I’d use the mini more for cleaning up hand pivot and keeping the barrel from getting pushed out front and tee and side flips. Good drills would be flamingos, pendulums and hover cloved. Can do all these with snap stops too where the focus is staying on the rear side, turning the barrel rearward and run into that pitch instead of reaching for it. But for front flips, I would def recommend fungo so you're NOT training to open up.
