After trying the less disrupting woolys, try using a long 6 lb. leader for working a small size 50 Hot Shot, tuned to dive straight, in dark green metallic &/or one painted flat black with a small piece of green lure tape by the tail. Use proper stealth by appraoching from way above the holding water and working the plug very slowly against the current down thru the hole, hovering it some. If the current gets too weak then slowly reel it up thru holding water. Try putting a very small piece of shrimp tail on the hook for a variant. -- Hey Bob, the biggest brightest thing I carry in my tackle vest is an oversize candy bar in a red wrapper. Might work? . - RT
