Your goal in this hand is to find the medium between getting the maximum value from your hand and forcing your opponent to make the biggest mistake possible. With a very small bet size, you give him too good odds, and with a very big bet size, you force him out. The bottom line is this: you should bet as much as you think he will call, without offering him the correct odds. How much he will call is basically something which only you can decide, based on your reads on this player.
As a general guide, I think that your 80% bet is perfect. It is attractive enough a bet that he will be compelled to call, and at the same time, clearly denies him the odds he needs.
It sounds as though you had quite a good read on your opponent. If this is the case, and you feel like you have little trouble putting your villains on a hand, you should start exploiting this by bluffing more in spots where you feel like you can represent strength and fold them out. Im sure you are disappointed that he folded, but imagine if you made this play with 72o?
