If the HT angle made a difference then how would you explain someone buying multiple Addict decks, all the same sig model, all with the same HTA but they last different lengths of time? My friend had two of the same Addict deck and he hadn't really progressed in the time between switching the decks but one lasted way longer than the other. Sometimes people have times where they ride harder than other times, maybe they have an off couple of months so they don't ride as hard or they clean up those sketchy tricks they have learned so their deck lasts longer.
