imho tarp is quite good for landing: its cheap and slides well; you'll ride away much further then on turf...
but sometimes you can catch an edge on tarp....
Dis-/Advantges of tarp / turf
Tarp = slides well, cheap, sometimes you can cathch an edge on the tarp if its laid down on grass or soft/irregular ground....
Turf= feels more like the real deal, you can hold an edge (where tarp just slides anyway you land), turf = more expensive, more friction, not enough speed to properly execute "afterbang"
