Another DLX fanboy (mostly AH, SF, Krooked and Thunder). Just consistently good quality, like the way they represent skateboarding (mostly) and great customer service.
NB Numeric, only big shoe Co I'm comfortable repping.
Ace. Rad product and the two main players have had amazing roles in truck and skateboarding history.
Bones bearings- quality, no other reason.
Quantum, only bearing Co that seems to be on par with Bones as far as I can tell but also cool to support two passionate dudes going for it.
My friend Murdey Surfboards makes amazing surfboards that easily perform as well as some of the SoCal boards I've invested in from time to time.
