self vs. traditional publishing

I have accomplished a great deal with the Titan books so far. Maybe not more than I ever dreamed (I can dream quite a lot), but definitely more than I thought I realistically could. From getting the books in bookstores to doing book signing events to school event and having them in libraries and having saes in the thousands I have been able to do so much and I am immensely proud. I do feel though that I am at a bit of a crossroads. As much as I want t be an indie author I feel it is a very difficult road when dealing with young readers, mine being mainly the 9-12 demo. Should I delve into the waters of traditional publishing? of course assuming I could find a publisher for Titan. What would I lose? What would I gain? I will be pondering this as I write Titan 3
