I shoot the 150 C (and 200 APO) on a 1Ds2 and while both are fantastic, the 150 would make a great TS - small, light, built-in hood, sharp, great 'pastel-like' color rendition, very well corrected for CA, smooth operation. Gorgeous bokeh from both as well.
I'm assuming the weight of the 200 would rule out it's operation as a TS optic (but maybe not) - but as hubsand indicates, it is one sweet lens. A bit front heavy and no way to attach a tripod mount, but the IQ... Does nicely with the Canon 1.4x as well.
Connor999: You should probably note which 150C you're shooting as there's 4 (the f4, the f3.8 L/S, the f3.5 and the f2.8), I'm assuming you've got the f4 or more likely the f3.5 as those are the most common of the 150's. I'd concur with your description for the f3.5 at least (Which is what I own).
