Yes there are a couple that are mind-blowwingly slow but for the most part, all of 7514 onwards seem pretty good. So I think that, if the X21 is as easy as it seems, I reckon E400's would be a very good buy.
People on here seem to make the X21 out to be a heavily demanding route just because it heads down the A1 (only a small stretch) but I don't think it is at all.
At least all this talk of E400s handling demanding routes fine is putting my mind at ease for when we get them on the Sapphire 7.
