I'm not gonna lie, I'm a massive noob when it comes to speedcubing. With a storebought cube using a really simple solve i saw on the internet i regularly get solves of 55 seconds to minute. I've had some recommendations for speedcubes and I can't decide between the a5 or the type f (II). Any help would be apreciated, also what does OH stand for? Sorry if it's a stupid question
