For me, my Continental tension hasn't been affected by learning to knit English. As for speedy knitting, there are English knitters who go really fast. So, if you want to learn Continental one day, great! If you don't, no problem! Enjoying knitting is what matters.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
