I was initially planning on doing everything at once but when I called Fortune yesterday to price out a set of the aluminum bodied 510, I was advised they are still in development, likely available in early 2019. If anyone else has an idea of where I can get a set of aluminum bodied monotubes built to order for ~$3000 let me know.
