Well, believe this or not...

The CG should be set correctly. Too far forward can actually increase snap tendencies
in some instances, because you have to use more elevator. Sometimes you can help
alleviate the problem by moving the weight toward the rear of the MFG recommended range.
(Thereby being able to use less elevator, and being less snap prone)
In any case, until you get very comfortable with the airplane, enough to adjust the
CG to suit your wants and needs, you should stay within design specs with it.

The Cap is a snappy airplane. The heavier it gets, the snappier it will be. (As wing load goes up)

Some count this as a "good thing", as snaps are desirable maneuvers to some of us.

Sorry, but I have to disagree with the "ANY" airplane statement.
Perhaps, if you have washout built into the wings, and if the tail surface is large enough,
and if the elevator control isn't too much... but that's a far cry from "any"

As for loops in general... unless we're talking about a funfly type plane... you should feed
in the elevator more slowly, as opposed to "pulling back hard" on the stick. It isn't required.

HARD elevator is what you do, in combo with rudder (& maybe aileron) when you WANT to snap
