The formulas are different. XFormula, STF, SPF. From what I gather the X is Dragon only harder. And that is how I would describe them after one session so far. I've not skated the STF though but it is a different formula as I mentioned. I'm sure the Skate One website will have it all broken down.
is it any different from Bones STF 99A? or its just the same? I'm currently using X97
Yes there is, x is more like a formula four, stf is like a classic wheel
