Does anyone find their battery grip to "wiggle"?

I decided to finally get a battery grip for my 2nd 5D to see what the hype is. I was doing some macro shooting today and noticed that it provides a bit of flex that I never had when shooting without a grip. I'm wondering if anyone else notices this. I don't think I have a problem with my grip, but rather that these things just introduce a new point of camera movement.

I think for macro work, I'm going to have to shoot w/o the grip and just mount the plate directly to the camera body.

Yes they do wobble a lot more with the grip on. When using it on a tripod, you'll need to take the grip off for any long exposure shots.
