i carry both stereo decks and Hi-Fi wheels and haven't really had any complaints.
i rode one of their older decks and it frickin ruled! but i haven't had a chance to ride one of their new decks(i'm hurt)but the people who have really like them. i'm waiting to skate the danny supa LP bamboo deck(7.87), hopefully sooner than later.
i swear by HiFi wheels. i've been riding the same set since feburary and they're still holding up nicely. no chunks, no flatspots, no problems whatsoever. thats not to say that they won't ever flatspot, if you sit on a power/bluntslide too long, every wheel out there will flatspot.
side note:
i wish my sales rep told me about these collab wheels and new decks when i placed my order last week.
