Sorry to hear you haven't been playing your horn but you seem to have a lot of fun with the drums so I guess it's all good. The poll is much in favor of removing. My take is that the first impression one gets is always powerful and a first impression of a horn without dents on a potential buyer is worth the little money you'll spend on removing the dents. I have to fix my cornet before I think about a flugel so I'm not game but could be if you still have it in a few months. Good luck.
