I wouldnt get a greyline from personal experience. I would get a SB2, Bluewater, or a G & M. Ive been striper fishing and keeping live shad for 25 years. If you decide to build your own I could help post some info on how to do one too.
I have bait tanks and fish stripers all over. I live not to far away from the area. I have a bait tank in my garage full of 10-14 inch gizzards if you ever want any company and want to try some live bait. I'm actually headed to the cumberland river in tenn in a couple weeks to chase the big river stripes over that way.
