Seems we are in agreement, there is no real need for a drag brake on the bike, however there is no real need for a lot of things in life, especially bicycles. GPS, carbon frames and bits, waterproof panniers, etc. yet we do involve ourselves in them. Shucks, disc brakes are not a real need as rim brakes are just fine and have served bicycles well over the past 100 years. Just go with the fun in the flow and get rhythm.
