I agree with everything said above. I use the BB and have good luck with them. They are very convienient especially when you are short on time because you can do a setup really fast. If you where to get the two shooters you can shoot about 5 different style of bumpers from them. You can adjust the arc height and change the bumper to get two different tight marks off of the same unit or flip one side around and shoot them like whats called a flower pot. Combine that with all the different bumpers that they shoot and they make some nice scenarios. I still think there is nothing better than using real ducks to train with but its just not an option. I can take a dog to work when its cooler, air them on lunch and breaks and then stop and train for a few minutes on the way home because I can carry all of the stuff with the BBS with me, Now if you have the money to spend get it all!!! lol.
