ATEC Tuffy Supersoft Dimpled Balls?

With indoor facility restrictions
(and reserved for about two hours),
I have had the most success with the use of:

a) JUGS Lite Flite balls (and used in an ATEC Hitting Streak.)

b) Mini (golf ball) size wiffle balls.

We complete the indoor gym hitting session
with an enthusiastic 45-60 min game of line-ball
using six outs per inning and typically
three five man teams .....that rotate

The Lite Flite balls are optic yellow for better visibility and will keep their original shape coming our of your pitching machine, regardless of the speed. Your batter will see a realistic pitch but won't get stung by the ball if it hits them.

We have had a blast with tennis balls - old ones that are beyond useful life on the courts are still great for BP - flipped up there from behind an Lscreen from about 30 feet. Kids love watching them rattle around the gym!!!

Are the LiteFlite balls solid enough to hold their compression for the most part while being shot out of the machine (we have a BATA unit which throws FB, CB, SL)??

I tried hollow plastic dimpled balls (higher quality - somewhat heavy - and will leave a nice welt if they hit you!) but they 'rise' when the machine is set on full power (70mph). Unless the kid comes up to about 30' from the machine, they'll get the rise.

So I'm in need of something that will still travel at 70mph out of the machine, maintain a realistic flight path, and not shatter windows or destroy basketball scoreboards when hit.

Krak we use incrediballs inside. We set up the L-Screen and throw live arm bp from about 40 feet. I dont know but could you use incrediballs in that machine?

How about this thing? It's website claims it is a "Pneumatic Tennis Ball Launcher, Potato Gun, Spud Cannon...."

Looks perfectly safe to me?

Lol..
That picture is awsome. I am perfectly confident that is the safest way to go and I doubt you will see any rise at 70mph
