Speedy is classic and great for everyday use. Epi Lockit is also classic but more formal imo. If you're going for mono, ebene or azur, go for Speedy. If you're looking to get something in Suhali or Epi, go for Lockit. Good luck.
Lock-it....I have one in Epi and I love it. The Speedy is great but it is so common. I also like the fact that the Epi Lock-it doesn't sag. The Suhali Lock-it is nice too.
I love both but between the two I'd choose the Lockit... maybe because I already have 5 speedy's and want a change, I'm lovin the Alma shape now so Lockit's the next best thing I guess!
