I've always set up my bikes to be purpose specific. This means different drops from seat to bars for each purpose. For example, my go fast ride for less than six hours at a time bike has the bars a good 2.75 to 3 inches lower than the seat. Conversely, my daily commuter, keep your head up to ride in HEAVY traffic bike has the bars about an inch higher than the seat. Sometimes more power, less wind resistance, and working different muscle groups isn't what I seek in a set up. With that said, glad the neck pain is gone for you. BTW, I've been using your exercise on very long rides and it seems to help. Thanks.
