I ride formulas on all my bikes except one and I am also a clydesdale 6' 240. Saying that, yes they are much better maybe not so much that you will notice a huge performance gap now as much as you will later(you get what you pay for).If you want something that will last as long as you do go with phils or pauls. Like jet sanchez said primatos are super nice also consider used dura ace or record hubs.
