I feel there are way too much trucks models and variations on the market.
We have Lows, Highs, hollows, inverted kingpins, titanium, 8 holes, cast, forged.
I really feel half of it is just gimmicky and brands should focus on doing less products and do them better (i.e. better bushings, better quality control, better pivot cups, etc.). It's a good metaphor of current economy, in a way we don't need half of the products/features we have, but just more durable/thoughts products, but that cannot work because our economy model needs constant replacement/renewal of products to survive.
