One who doesn't make mistakes, hasn't learned much. Dive in while the water's warm, take your lumps, and enjoy the swim. From a learning perspective, and with the exception of relic guns, there are few double guns that can't be enjoyed. My dad said to buy the best you can afford, and you'll never be sorry. While I generally agree, most doubles have something to offer, and to learn from. No one ever stops at just one. My two cents.
