Don't do that. And forget about your weight, just think about what you want to do on the bike. Do you want to commute, so you need to carry a change of clothes, maybe a laptop? Make sure the bike you buy has fittings for a rack so you can put on a pannier or two when you need to. Just want to go fast and have fun without carrying anything around? Get a road bike. Want versatilty? Get a cyclocross bike or a tourer - in my opinion these bikes will do anything a hybrid can do and are lots more fun to ride. Buy a hybrid only if you want both versatility and an upright riding position.

None of this has anything to do with your height and weight. A superlight carbon road bike will cope perfectly well with your weight as long as you don't fit it with superlight wheels. 16 spokes wouldn't be a good choice. Get a robust wheelset with 28 or 32 spoke per wheel and a road bike would be fine... if that's the style of riding you want.
