Splitter vs. forkball

most effective?

my fork tumbles up to a foot

my splitty doesnt break as much as my fork but has only been practiced for about 5 mins.

Obviously right now it is your Forkball. If it breaks that much and is DECEPTIVE to hitters which is the most important thing then you found an offspeed pitch.

thing is… ive never really pitched to a batter. ive only been pitching for about a month.
