its all preference bro i ride 81.5 and i rode 83 for about 5 months and i always hated it but if your more of a flow rider and you ride a lot of minis and just going big without tech yea get 83 because its more comfortable and you have more space but if you ride a lot of tech and street get an 81.5 because the steeper the headtube angle the harder it is to whip cause i cant double flat with with 83 and 81.5 or anything less i can no problem but try riding some other peoples decks to see which one you prefer
