Spinners and leeches are good livebait options for summer walleyes like this one caught by Rob Lane.

When considering summer walleye presentations, the terms spinners and crawler harnesses are often interchangeably used, so strong is the connection of spinner rigs and nightcrawlers.

Soft-bodied crawler imitations are experiencing increasing use, but they still represent duplicates of the time-honored dew worm. In certain scenarios, though, folks are overlooking a tremendous spinner tipping option: ribbon leeches

Combining spinners and leeches can be an effective tactic in a variety of summer angling situations, but I've found the setup to be most useful within fairly defined parameters.

Two of the factors are submerged weeds and panfish.

The undulating action of a ribbon leech has an obvious bite-triggering quality. But its most significant attribute might be that of toughness. Pull a leech through weedy cover, where it is going to frequently hang up for a moment, and it will stay properly hooked most of the time.

Natural crawlers often tear free from the front hook, rendering the presentation ineffective. A lot of time is spent winding in to reposition or replace the crawler. It won't happen nearly so much if you are using a leech.

Clear or lightly stained lakes, ones with considerable levels of submerged weeds, are best suited for spinner-leeches.

Within the scope of finesse-to-coarse presentations, the spinner-leech leans to the subtle side. It has more in common with a slip-sinker bait rig than the typical spinner-crawler combo pulled behind a bottom bouncer or three-way rig.

Visualize the spinner dragging slowly through thin, transitional weed cover with just enough speed to keep the leech stretched out. Lightly snagging on occasion, then breaking free, an action that turbocharges the spinner blade, temporarily sending it into warp drive.

Leech-spinners are at their finest when worked through the sporadic weedgrowth found along the deep and shallow sides of the cover.

The best sinker to accomplish this is a bullet-shaped slip sinker, commonly used for bass in conjunction with Texas-rigged plastics. Weights of a half-ounce or three-eighths of an ounce are right for weeds edges in the 10- to 15-foot range. Scale back to a quarter-ounce when working shallower weeds.

If these weights seem light, that's by design, as it necessitates a slow boat movement.

Whether you prefer to control the boat from the bow or stern, either is all right. Whatever you are comfortable with. The main thing is to slowly move along, allowing the spinner-leech to do its thing along the fringe of weeds.

Keep the line angle about 45 degrees. Electronics play a big part of proper boat positioning, as the sonar screen will display the zone of thinner weeds. The trails feature of the GPS allows you to fine tune your positioning during later passes.

Use icons to make note of where you need to hold tighter to the cover and where you should move away.

This isn't a deal that merges well with rod holders. As one might expect, such a presentation calls for handholding the rod. Since the spinner might not consistently rotate at such a slow boat speed, occasionally pump the rod to kick it in gear.

A final thought on presentation: This leech-spinner-weed thing is especially effective at night. And the offering need not be quite so precise, as the strike zone tends to grow once the lights are off.
