mr catfish, if you are making ACCURATE 30 yd casts you can catch anything that swims in green river lake (if youre in a boat lol).
now that you are getting more comfortable making casts without backlashes start concentrating on the retrieve. different speed reels can be deceiving. tie a floating lure on (zara spook or whatever) , make your cast and start reeling as you would normally reel. watch how fast the zara spook comes across the water, now visualize how fast a sub-surface lure would be moving at that same retrieve.
if you were fishing a jig for example imagine that everytime you turn the handle on a 7:1 ratio reel you are moving the lure 24-28 inches roughly. now if you pitched that same jig to a stump ad turned the reel handle only 5 times you are now over 10 feet away from the stump
learning to visualize what the lure is doing under the water with different reels will help a bunch.
good luck
