No...........they won't help in a truly significant way. The cost will not balance out for the tiny % gain. If your current pedals have traction and your shoes are soft enough to grip you can pedal in circles just fine. I have used toe clips, power grips and SPD 'clipless' and in the last two years I have returned to no retention and large surface area (important) BMX style pedals with traction pins. If you want to climb better get your body weight down, if you are carrying extra. Thats what Lance did and it moved him from a mid packer to a front runner. If your hill is a challenge, lower your gearing so you can maintain a proper cadence. Keep riding and eat and drink correctly, not excessively, just enough of the right stuff. When you are not used to something, it takes a while for you body to recover. You can over train if you push yourself in the beginning. Depending on your age and condition you may need to ramp it down a little. Lowering your gearing will help a bunch to reduce the anaerobic strain on your muscles allowing faster recovery. Most road bike gearing is too high for the average rider. You also may want to get enough sleep if you are exhausted. One other thing to try is to purposely tone down your pace by about 15-20% and see if that allows you to recover better. Often we bike nuts are prone to throw good money at gadgets and 'super light component thinking', when what we really need is some common sense.
