True on that when close to the bottom everything down there will take a bite of your worm. I just take long turns and stay up in the water column mostly. I have had my share of troubles with dispys too though when it comes to grass. especially when the surface it covered with them and they run down your line. Have you ever reeled in your dipsey only to find it has been winding up your line? I've had some crazy looking springs/ bird nests a time or two. lol There is good and bad with all of them that's for sure.
