Although the Langton rules have some good bits they can be overly realistic. I was just putting forward the notion, as with WGS, by retaining the chit system it would be simple to decide whether a tack was successful or not. then it would be successive red cards (taken aback) until a successful turn was made. I don't know the % of zero's to number damage but whichever is the least should be the failure. Of course all special damage would be ignored.
