Firstly, If the F18s have a fleet, they are not going to let the F16s play with them. They don't need them.
Secondly, this is the first class I have heard off that are arguing to have their rating increased (reflect the boat is faster). If you believe it is a gift rating compared to an A or F18, you are a fool to ague agaist this advantage. No other class will.
It only sounds like little brother syndrome and nothing else. The F16 class is better than that.
One F16s opinion that all F16s and F18s should carry the same rating does not represent the entire fleet. People are only stating the obvious in terms of relative performane. Yes, it is close but not the same.
Just the same as light F18 teams might find a better fit on an F16, heavy F16 teams might find a better fit on the F18. No need to bash one fleet or the other.
