Shops that offer FBV are few and far between, heck most don't even offer hollow choices, I doubt they'd invest in a FBV machine with all the different options. They are content to offer a "regular" that everyone gets. We see teams from all over the country when they are in town for tournys. Most give us the deer in the headlight look when we ask them what setting they would like. CB1, having a spare set of steel is always a good choice, especially when in the first period you or your son loses an edge or breaks a runner and the pro shop is closed. Being able to pull a runner out of your bag is priceless.
