I wonder if there's some help out there for an amateur angler?

I have trouble casting light lures (such as smaller size Rapalas) with my spinning tackle. Can't seem to get any real distance on my casts.

Can someone give me some basics on the tackle, line and techniques that will give me some better success? Using a Shimano Sedona spinning reel, a medium-lite Ugly Stik, and 6 lb test.

Thanks much,
John
