Hey does anybody have a Storm Rolling Thunder 6 Ball Roller...... If so can you make a video on how to make it a four ball bag !!! Thanks !!!!!!

I've the 6 ball roller and making it 4 ball is quite easy.  Simply remove the middle tier (make sure to 'unhitch' the snap) then set the top part on top.  You will have to adjust the strap (attached to the bottom rear) to accomodate the short distance.  There you have it!
