Yesterday while fishing a T-rig spider grub I was reeling it in quickly.  It was barely under the surface so it made a ripple on top with the twin tails.  Has anyone ever tried to fish it that way  with any success?

Yep, and it works in the mid ranges and the deep dropoffs too. Its a great Fall tactic

Chris, what size weight would you use for a 5" grub?

I have used the 4 inch one from BPS and the 5 inch from Yamamoto baits. You fish it like slow rolling a spinnerbait. You can use a football head or a XPS Grub Heads that look like a shad head. Because the line tie is ontop of the head on the XPS jigheads, it swims a little different.
