Need some help with the vaporizer guys...when I try and go from stoner control and roll to get to the vaporizer I seem to be getting stuck and am unable to complete the roll. I can just reach down and grab the foot to get the tap just fine but I would like to master the roll. Im a small guy and most of my opponents are larger than me and are stopping me upside down when I start to roll...any thoughts would be appreciated. Thanks
