I used to run rear drag reels, mostly Shimanos, but I switched to front drag and have never looked back. Most new reels don't include a spare spool and for the price you could nearly get a second reel. You may want to consider the Pfleuger reels (President, Supreme, or Supreme XT). I have an Abu Garcia Soron that I really like. If you go AG, go Revo. The Orra series is not good. Sons Diawa Aird came with a 25 and 30 size spool which was nice. Don't think they make the Aird anymore though.
