Replying to Grabbing on rails

So I recently started incorporating grabs into my tricks on rails a example like a fs 270 on and then when on the rail u grab truck and then spin off.....I found I really like doing grabs on rails and it looks kinda sick....but I almost never see it done... Do you guys ever see or try grabs on rails?.....i know on big up rails I will see grabs spinning off but I really almost never see that.....thanks guys let me know if you ever try grabs on rails or see them much.
