My understanding is that the Duck poles are more like the BGJP than they are PST. Dont care for PST and after my conversation with the lady in West Point doubt I will own anymore BnM poles, but thats just me.
With that said for the price you are talking for new poles you wont be hurt either way, if you dont like em you will be able to sell them with very little loss, good luck which ever you decide on.
