I recently went through this same debate with several people. Here is what I learned.

The full scale Extra 300 did not have counterbalances.
The reason a lot of models have counter balances is to assist the servo. However modern servos have enough power that this is no longer needed.
No counter balance is less likely to flutter than one with a counterbalance.

Personally I like the look of not haveing a counter balance and that is what I am doing with my 300.

Just be sure to get a good link aka mechanical advantage with your servo vs the elevator and you will be able to 3D or fly Precision just fine.
