I prefer a turnaround kago, or neutral dboost.

A turnaround kago can work but from what I'm seeing, it leaves you with significantly fewer i-frames (looks like it takes some time for the turnaround animation to finish before you can begin running?). Holding forward boosts you down and you begin running more quickly. It doesn't seem to matter with the 3 Waver hit version since you'd be falling off the runway before running out of i-frames either way. But with the 2 Waver hit version, the holding forward method seems noticeably more lenient. https://videos.maprando.com/video/7201

I might be missing something about the neutral dboost because wouldn't that push you upward, delaying the landing so there's almost no opportunity to gain enough speed to cross?

I didn't see that there was a 2 waver hit version because the parts for avoiding firefleas obfuscate what is important to the strat.
2 hit jump fits in extreme because I think you want to set up a visual cue for where iframes run out to do the jump. I'm not going to use it if I can avoid it, but farming wavers before that point was overall harder. Turnaround kago could work, but was harder.
