I am looking in to buying my first shotgun, and while choke shopping I had settled on getting a modified choke for all purpose shooting. The choke I was originally looking at was this one. Then I was looking at chokes on Remington's website and I found this. My question is are these two chokes the same or are they somehow different? Remington and there use of terms like "Flooded Timber" or in this case "Over Decoys" has me really confused.
