Congrats! I do not think you will be disappointed. I'd suggest really considering the triangle in a square in whatever block side you most often make. Also, the BOBs are really a nice addition to your die library. The Lemoyne and/or Hunter Star is a good starting point.
I recently purchased a Winding Ways BOB and much to my surprise forgot I already had it until I was placing it on the storage shelf. I had also already purchased the fabric to make the quilt which makes this purchase all the more a "what the heck moment". LOL
Enjoy your purchase and making more quilts.
