Good for you... Bob makes a wonderful bow and his are not only beautiful.. his craftsmanship and the performance he builds into his bow's are second to none. But then again if you read below my name you'll see I'm a bit biased.
I went thru several [ 40+ bows ] before getting my first Morrison form Donald Rowan here on TG, a 62" 62# Morrison "Take Down"... Beautiful bow and the fastest Trad bow I have ever shot or owned. [ Do not get the idea you need 62# !! I have been shooting trad since 1962, and shoot that wt. regularly. ]
That 45# Dakota should work for you just fine. But, as I stated earlier on your post be sure the bow lenght is compatable with your draw length.
