88, mid level of a party multi

[iMsoLucky0]

In this hand, Hero is table chipleader with 4400 and villian is average player with average stack with 2800. The blinds are at 50 100, and hero is dealt 88 in the cutoff. Villian in early middle position makes it 400 to go. Hero calls, all others fold. The flop is 2 3 5 rainbow, and Villian bets 425 (half the pot).

What is hero's line from here? I will post my chosen line and what I think to be best after some responses.
