Using Kinetic sand for front rest

[REastman]

Has anyone played around with using something like this

for sand in the front rest. I am wondering if this type of sand would have less tendency to "flow"
down from the ears into the bottom portion of the front rest bag during the course of fire in a match.

Let me know if this has been tried and if it made any difference.

Thanks,

Brought to you by same people that marketed "The Pet Rock".
Seriously, the bullet points claim "sand in motion" which would not be good...yet it claims "to stay clumped". The video did not work for me.
I use Black Diamond blast media from Tractor Supply in the bag ears.

For Rear bag ears and Front bag, stick with traditional playground sand. And don't forget to occasionally fluff up the front bag.
