Putting a big chunk of my roll into PP to try to clear their deposit bonus. $500 means that I could potentially play NL$25 which seems to be a good way to earn this bonus.

My problem is that I am a SnG player and NOT a ring player by any means. With that in mind, should I play NL$10 instead (I'm assuming this exists)? How much slower would it be to earn the bonus this way?

I am not there to play ring, I am there to clear the bonus. After the bonus is cleared, I am playing SnGs again. So what is the smartest way to do this given the fact that I don't usually play ring? Perhaps play NL$10 at first and then move to NL$25? But then again, if the game at NL$25 is beatable for a sound TAgg player, then I may as well just skip the NL$10? Can much be gained from playing NL$10 first?

I have done an extensive search on the differences between NL$25 and other limits and also on the transition from SnGs to ring. I found these posts particularly helpful:

Additional thoughts are appreciated, especially if you're a SnG player who plays ring just for bonuses. Thanks in advance.
