My tektros feel spongy. I currently just have the stock pads on them and they're being pulled with Campy Record 10 levers. The levers might be some of the issue. I have the tektro on the front but haven't gotten around to changing the single pivot 1st gen dura ace out on the back. The rear brake feels much more firm in my hand and from what I remember, the DA brake on the front felt more firm than its replacement.
