One thing I forgot to mention in the review is that the Spike that comes with MP-45 is entirely different to the one that comes with MP-44. Most notable difference is the lack of hard hat, but it would appear it is an entirely different mould altogether when examining them side by side. The legs on the MP-45 Spike don't pop off anywhere near as easily as those on MP-44 and it's also easier to balance. On MP-45 Spike there are no magnets, which makes sense.
