Athena here, same same problem. I had the perfect bike professionally spec'd out for me (I'm well within your weight category :)), this is what I was advised on (oh and I bought a Litespeed):
FRAME MATERIAL: ideally, Titanium, with a combination of a 6/4 downtube and 3/2.5 for the rest. Another great option would be a good steel frame, something along the lines of a Reynolds 843, or Columbus SLX tubeset.
COMPONENT SPEC: For wheels, either a pair of Mavic Open Pro rims, 32hole, built on Ultegra hubs, standard lacing, 3cross for the rear wheel…or a pair of Mavic Ksyrium Elites. These wheels are pretty bomb proof, no matter what you throw at them.
i wish ksyriums were bomb-proof. i trashed a pair in just over a year of normal riding, and only 1500 or so km's. i was just over 200lbs at that point, but they went out of true, and we could never get them fixed again.
went to open pros to 105's, and they have been immaculate since.
