Mako sizing should be equal to Bauer sizing. I'm in a 5 in both brands. If memory serves, CCM is 1/2 size bigger than Bauer in most skates of equal length. Agree with IP, I'd go down 1/2 a size.
Agreed, I've had mine a month and a half at this point and sharpened pretty frequently on it and haven't had any kinks. I'd go for one if you are interested it.
