why won't you just use hp drain 7 in this?
imo with it that spinner is still harsh, but come on, not in that way that you've got to spin 400+ all the time... this would be ridiculous, if some person would get a SDH (single digit hundreds) on it or something, and then boom! failed because of drain. the spinner's length is fine and i really approve it, so imo the best solution of this is just using lower hp drain. :)
also, sick map, i'm playing this almost every day, and yet why i haven't starred it?
