prop suggestions

thinking of a prop upgrade this offseason. Not sure what to get. im pretty much clueless when it comes to prop selection. My boat is an 05 outback. i have a fat seat in the back and looking to add a sac in the nose under filler cushion. I wakeboard mostly and slalom a little as well. and then the family tubes and what not. Not trying to break the bank but want an upgrade from the stock prop. hopefully the old outback gets replaced by a mojo in the next year or so. I do plan to surf a little. Im terrible at surfing but it intrigues me. thanks for any insight
