Rob,
I have used the carry-lite with good success in Illinois but never really used it around here because I don't ever hunt fields where I live. I really like the looks of that decoy and I don't think it is too big. It's on the bigger side but it's the most realistic looking decoy that I have seen (although I haven't looked at decoys in the last few years). I think the realism of the decoy will overcome the size. Now that being said, if they had a decoy that was as realistic looking but a little smaller then I may opt for the smaller decoy. But, I think you will be fine either way and I predict you will kill a 154" 10pt on the 3rd day of your hunt using the decoy that you posted
Good luck buddy!! Nothing but good mojo coming your way!!!!
