I agree that a small light best is great on quick hunts, or hitting corners. Thanks to HUGE 4wd tractors, we walk 1-mile fields with 2-6 GSP's, those big water bottles come in handy...for the dogs. Also, in the Texas Panhandle, we may start out at 0 degrees and finish the day at 60. The Wing Works holds what you need in those type of hunts.
I use my 6 year old Filson that is soft as butter for those short and quick runs. Have also thrown shells in my pocket and tucked pheasant feet under my belt...had just as much success and best of all...fun!
