Whats your opinion on Seasoned and Tuned Ball Bearing RC's or SG's.

The ups and downs of this method, ect..

For tuned/seasoned bearings:

Advantages:
Greater survival/life after death
Poor balance
Low spin rate

Disadvantages:
Poor Balance
Low spin rate

I prefer to not use tuned/seasoned bearings, you get poor balance. And balance is just to important to risk.

Yes,but if you sacrifice balance it would leave you with a wobbler.

I don't season/tune my bearings just because they work fine the way they are.
