The difference doesn't really matter when you have the right size of liquidity flowing in. The yields controls what happens entirely. It would currently be crazy to have cubs sitting around right? Why exactly? Because there's literally a way to earn about 40% more.
So that makes it hard to want it floating. No doubt people will occasionally want their money back, but I believe the reserve cannot really run out if liquidity, that alone would break the peg if am not mistaken.
The fees can be earned but the liquid portion required for the bridge can't really be put to work. So that means that PolyCUB will be subsidizing most of the APR and it will take away from the other pools. There is only a certain amount of PolyCUB per block and it can get diluted quite fast if there are too many pools.

True, this is where polycub governance comes in, every pool cannot be rich, so if your have a favourite, get more polycubs deposited into the xpolycub vault to gain more governance power, so as to vote your favourite pool to get more yeilds allocated, with this, Polycub price is sure to do well and so will the entire platform.
With money comes competition, and that requires power to win.
