I got a Doghouse blind for Xmas and was wondering if anybody had any experience with the shoot through windows. Do they effect the flight of the arrow other than slowing it down? Also, I am using Spitfires so I guess I will buy some Muzzy's. Has anyone ever shot a mechanical with the blades open? The shoot through windows seem like a good idea and they are part of the scent control with the blind but it seems like it would change the direction of the arrow. Thanks
