ummmm....
All this looks like are those plastic bristle things they've been using for, well, several decades now. Although the quality looks a little better I'd still be afraid of some serious rug-burn type deals if I fell on that. Not to say I wouldnt use it because I'll take what I can get in the off-season.
Anyway. Yes I would think you can groom over this stuff, or just take it down before they make snow, which is probably the most logical choice I can think of.
