okay ive recently purchaseda sidearm pro i thought they looked pretty good i spent 10 mins in the garden chucking out tennis balls i seemed to be pitching them halfway dow the track and at an so they started well outside off and got wider going towards 3rd slip. the tennis balls were slightly loose dont know if this matters. also can is use incrediballs and kids cricket balls in them.
also any tips on how to perfect my action throwing it as in wrist and arm action e.g should i flick it and stop or follow all the way through ???
and is the pro suitable for kids unders 13s and 11s to face it.
