Unless you have actually decided you don't like your superposed anymore, you should not trade one for the other. If you do you can't make a comparison for one thing and 2nd if you don't really like the BSS you won't have the superposed. I'd reccomend you get a BSS you think you like and find out which you don't really need anymore. Then the worse that will happen is that you will have two guns you might sell if the offer is right.
