Yeah, this guy doesn't (as he admits) understand a skaters mindset or culture. If you ride Indy's you're buying into classic solid trucks, and if you been skating a long time you are likely to be nostalgic.

On a more practical aspect, you don't want to relearn the feel of your trucks, and for what benefit, if the word was they grind better, or are lighter without a reduction in strength, maybe, but neither are likely to be more than marginal. Also skaters can be a bit superstitious, have a crap session, blame the stoopid new fangled trucks.

Anyway may take on it, but not skated for years.
