Re: i may begin fly fishing... questions and advice?
Personally I wouldn't try putting on mono on a fly reel. Its not built to cast straight off the reel like that and you can't fly cast just mono. What you could try is bringing one of your casting reels along and putting it on the fly rod when you want to switch tactics. Reels don't take up that much space in a tackle bag. Keep in mind, the fly rod is built to load fly line when casting and not mono (if your trying to fly cast with mono...it wont work properly) and its also not really built to dead lift a decent fish. You would want to be careful landing a fish if you did that.
Having said that, it might be fun on a lazy day to bring a spinning reel to replace the fly reel for some good ol' bobber fishing. I know my crappie rod is longer than my fly rod, so casting wouldn't be that weird.
The thing is, if you buy a starter kit and don't mind if its in pristine condition, give it a shot. Just keep in mind that the fly rod wont have the backbone that the med-heavy bass rods have.
