Since you want to try different barrels, I would say sell it and buy the standard Encore. The Pro Hunter only offers a little more "bling" and the nifty hammer. I haven't heard any reports about the 90 degree breech yet. Get a Limbsavers recoil pad and your'e set. And you'll save several hundreds of dollars.
Barrels and accessories will interchange between the standard and Pro Hunter Encores. I have several barrels for my Encore and enjoy shooting it.
