personally i would get 43 pray, because it helps a lot in many different ways, and u can use any of the protect prayers to help u last longer....
also, 58cb isnt too bad....the only thing i would consider is that do you prefer quick 10 rate games and not mind not having the prayer?
or do you want longer games, with some extra charges with the prayer, and get more than 10 rates a game...
this is kinda how i see the situation....but, in general also, if you fog in a noob world (e.g. world 1), fiting plenty of noobs without prayer wouldn't be much of a problem to me....
