8-16 1/2 kill

[setzf]

i've recently moved and my new card club has some juicy games at 8-16 with a half kill, ie if one person wins two or more in a row the game is played as 12-24 with the winner posting an extra small blind. i've never played in any kind of kill game before though and was wondering what kind of strategy adjustments might be needed. also should i even sit in on the game if i don't have a comfortable 12-24 bankroll but do have a comfortable 8-16 roll?
thanks in advance
