Any dryslope will eventually wear down your bases. Its a matter of friction. Msnow is by far the best product available. Snowflex does not deal with anybody or company that is small. I.e Liberty Mountain. So unless you have hundred of thousands of dollars to spend. I would lean towards Msnow.
Your best bet is Msnow, as stated before you actually have control, turning and stopping ability. You will never get these qualities from plastic fencing and astroturf. Plus it needs no lubricant or H20.
I am very impressed with the stuff.
