Interesting thread. I had one suit made by C&M about 8 years ago. Very similar commission to yours: 13 oz Lessers grey nailhead, 3 piece, SB peak lapel, but with a vest without lapels.
Joe Morgan is a great guy -- very personable, professional, and a perfectionist. He has a definite house style, which one must buy into if one is to be happy with the result. Yes, he can accomodate requests around the margin, such as ticket pockets, shape of lapels, etc. But your suit will look substantially like the silhouette depicted in medtech's basted fitting. In fact, his suit at this early stage has the same shape as my finished suit.
At the end of the day, there is nothing wrong with my C&M suit. I was just never comfortable with the style. Again, to be a happy customer, you have to like the C&M silhouette. I gave it a try and it is a good suit, but I find that I gravitate towards wearing suits made by other tailors (and some RTW like RLPL).
