Bill the spoons you mentioned are more casting spoons. There are endless number of manufacturers of spoons and colors but I have narrowed the shapes and sizes to two I like on Beaver and that is a long narrow spoon for whites and walleye and a fatter shad shaped spoon for Stripers. Neither of these resemble the traditional bass jigging spoons that work well on LM and spots, not what I am after.
I have sat on whites and caught 30 of them with a long minnow shaped spoon and had a shad shaped spoon just hanging in the strike zone without touching the rod and had a 20lb striper hit the fatter spoon. I don't know why, just what I have seen and my experience.
One thing I have noticed about stripers is that round black dot you see on the side of threadfin should be on your spoon, I carry a sharpie for that.
I like the real image spoons at Cabela's but my favorites are made by an older German lady in Killeen Tx who is caring on her late husband's design under KT lures. HLS sells two models in the same color but there are many more on her web site. If you like them I encourage you to call her and tell her, she is a really nice lady and loves to talk about her late husband and the bait shop they used to run together. She no longer runs a store front and sometimes gets slow in her production since she works alone, but she makes one killer spoon.
I don't claim to know all about spoons, just they are may favorite way to fish for anything except blacks then I would say drop shot. Also don't overlook the cheap spoons at Academy, they are great around trees when you are going to loose a spoon $1.50 is not hard to swallow.
On weights I like the 1/2 oz for the action but over 30 feet I like the 1 oz so I can get back on the action faster.
