Depends on who you aim to stake, and what amounts. You won't find high stakers around that level/stats anymore. Personally I'd go for a boxer, stay 1 payer and aim for around 70/90/70 with 80ish HP.
You really don't need a 'staking account' per say. With the use of the highscores and such, if you're trying to trick people around your level it may not prove fruitful.
