I didn't vote because I have a similar dilemma. I recently got a mint RatMastiff and while I know I will use it eventually, it is hard that first time because it is so pretty. Thankfully I have a user Ratweiler to beat on while I decide on the RatMastiff. I say take your time before you decide one way or another. If it's a definite keeper than I would say use it, but if you think you may want to sell/trade it down the line it may be worth keeping new.
