Greg: Build quality on either will not be an issue. Both are well made and in wide use. They are of different designs and only you can decide which you prefer. That can only be done by shooting off both so you have some facts in front of you. It will be a rare ARA match when both are not common on the line. 99% of shooters will be happy to let you "borrow" their rest for a ride during practice times. If that is not possible for you, both have good resale value, and if you choose one and then want the other recovering most of your initial investment will not be difficult. bob
