Has anyone used a shad colored tube? If so what brand? I am Looking for a good Shad colored tube to try in some lakes that I go to. These lakes are heavy with Shad so I am thinking this would work well. I am always wanting to try ideas that pop into my head. Any info would be great. 

take a spike it marker and a sharpie to a sliver or white tube. 

I think any smoke-colored tube would fit the bill.

Bass Pro Tender Tubes have a terrific array of baitfish colors. There's a smoke with chartreuse flake tube that just kills the Mille Lacs smallies.

There are a few on TW under their tubes section. Big Bite has some in various lengths and at very reasonable prices.

Dry Creek makes about every tube color known to man!

I carry white flipping tubes from Strike King and fish them like a fluke. They can also be fished like a toad across vegetation and killed in the openings.
