I've proven to myself that static can be as accurate as dynamic, if not more so. I'm sure this can be debated, but here's what I've done.
I static-balanced my front wheel and took it to cyclegear (they do free dynamic blancing). Machine confirmed that balance was perfect.
I then intentionally added half of the 7 gram weight to the wheel (meaing ~3.5 grams). Took it in and machien still showed perfect balance. On my static balancer, I can see the 3.5 gram inperfection and can correct it.
Does it translate to a rider feeling it at certain speed? No idea.. just saying.. static is very very accurate when done right.
