I commute exclusively on laminated bikes because I broke too many metal ones:

every day commuter A: orbea carpe-diem, ultegra compact/770 shifters, xt hydraulic dick brakes,
rain/spare commuter B: trek 7.9 (free frame), ultegra compact/770 shifters, front xt hydraulic, tektro rear,
training ride/hammer on a sunny day commuter C: taiwanese frame, ultegra compact/brifters, tektro brakes
