Put your order in for a new Shrew with Ron. The list is not getting any shorter. Also, you can make sure you get the Shrew that is perfect for you. If you have the opportunity to buy a used Shrew in the meantime you can always shoot it until the one you ordered is ready and then sell the used one for what it cost you while making some other lucky buyer happy. It's called recycling!
I have 3 Shrews on order and will be getting the first of the three next week. In the meantime I bought one for my wife from the classified ads here on TradGang! You can see I am practicing what I am preaching.
You also say you would like a Morrison Shawnee longbow. That is an incredible bow that I highly recommend. I know you can find one of those in short order if you want one. In fact, you can probably buy one that is in stock in Bob Morrison's shop right now. The only trouble is you will not want to sell the Shawnee when you buy a Shrew, and then you will be faced with a terrible dilemma -- unless like me you are inclined to own 30 or so bows.
You will undoubtedly love either a Shrew or a Shawnee -- or both. They even have 4 of the same letters in their names. What a coincidence!
