Yeah I understand. It would seem rather narrow if I just did pedal grinds 24/7. But, it's just the only type of grinding I'd consider trying first on a rear pegless bike, and then expand my horizons later on, so to speak. 1-trick pony-ism is not my goal for BMX. I'd personally rather get some other street things done like large kicker hops, barspins, crankflips, spins, fakies etc.. and so on. Grinds are just a small part of it for now, but are so satisfying when you get it picture perfect . It's just that forward pedal grinding seems much harder to keep the bike balanced in position and upright. But I guess grinding on the crankarm solves this, but I much prefer pedal grinding to the backfoot (rather unicycle-esque).
