Good hooks will stick to your skin. I've been using some spinners that I ordered from Cabela's and I have no complaints. The Quest Championship Walleye Spinners, in particular, trail nice through the water and are tied with good line, components and hooks. Taking spinner rig balance a step further, make sure the bait is centered on the hook so the bait doesn't spin. Sometimes if the crawler or minnow is hooked off center in the nose, the bait won't trail behind the spinner right.
Leeches are the hardest bait to get to run behind a spinner without spinning.
I sometimes step on the leech to kill it and then hook it through the narrow end. Crawlers are probably the fastest bait you can run while leeches need to be run a little slower. Bottom bouncers and spinners can be run at a variety of depths and speeds. As long as you are moving fast enough to keep the bottom bouncer standing up and moving slow enough to keep your line and bait from twisting, there is no wrong or right until you catch fish. Changes in speed often trigger strikes, however.
