I saw and handled gamblor916's MP Grimlock today. My very basic & brief overview: this toy is 45% Masterpiece, 45% upscaled G1 toy, 5% gimmicks. The toy does have quite a few gimmicks, but they don't overwhelm the toy nor detract from the overall engineering. Basically the lower half of the toy is like a Masterpiece in terms of complexity and ingenuity, whereas the upper half is fundamentally an upscale of the G1 toy.
