Well i had/have (still in box, just in case!) a 456 summer season that was ace but a chore needed to be slightly steeper imo, should of got a standard but the ss was v cheap, so decided to get a standard 456 when the Mmmbop came upat silly price, or should i say cheaper then the 456 so took a punt and tbh thats ace as well, is it better, not sure yet but definately hitting stuff faster, and not always by choice it just seems to be more eager/rides faster, buts that just imo all that steel is real stuff, cant say i noticed that either…anyway enough rambling both are ace, but tbh i wouldnt of got the Mmmbop at rrp as i dont feel it is that much better 😮
