Do you think hitters and swingers use different pressure point combinations to regulate thrust ?

Is is possible to developing a swing that uses all 4 pressure points, but not necessarily a 4 barrel swing.....and if so, is there any advantage ?

My opinion,
#2 It may be possible, but not all consciously .No advantage.
#1 They can-I would say swingers are more likely to use #2 than hitters .Hitters should have no real use of #4.swingers are more likely to use #'s2&3 .
Both are more likely to use just #3
