Two different cash tables at a house: which one?

First of all this is a game that will be attended by college-aged people and there will be two different cash tables. A .25/.50 with a min buyin of 10 and a .50/1 table with a min buyin of 20.

I have only played once with these people at the .25/.50 limit (since that was all they offered at the time) and I felt I could definitly beat the game. However, now that they have two limits what would you guys recommend I do?

Assuming that the best players all decide to play at the easiest table, would it then be correct for me to play at the highest limit one due to the fact they might see the .25/.50 as the most profitable table?

Any help on solving this game theory type quesiton would be helpful.
