I think you made the right choice. I just came back from the local HD shop, I wanted to check out the Harley one. It only has the 2 positions, angled and 90 degrees. I thought you could also have it straight, which would clearly be out of the way.
I don't know what the material is that HD uses, but it was light. Walters says that they use chromed steel. I think this will be heavier but also more solid.
Now the choice solid or billet style.
I think I will get one before next riding season. Let us know how you like Walters!
