Not sure if Akiko was first historically, but I recall Alaine Chartrand had a nice change edge haircutter layback too (saw it in her 2015-16 programmes).wasn't it Akiko Suzuki who did the change edge catch foot? i remember she was the first one i saw do it, and was like woah! way to make up for not doing a beillmann and it's a crazy hard feature.
Are the Kim Yuna-style (leg in front) and Lipnitskaya (leg by ear) styles both classified as I-spins? I kind of get what she means; with both versions the arms tend to look a bit 'grabby' and the foot is flexed. Sometimes the leg-by-ear variant is held too long until it comes to a standstill too.She also hates I-spins because she thinks they’re ugly unless done the way Kamila Valieva and Mariah Bell do them.
I'd call Mariah and Kamila's a V-spin (Anastasia Gubanova does a nice one too). The upper body tends to look less strained in that position, it's very similar to ballet where we stretch at the barre in ecarte position. It's nice because it lets the skater point their toe and hold the free arm out overhead.
Now we've definitely ventured into flexi territory here, but never mind
