Sup mane. I haven't gotten results yet, as I have just "taken" the test today. Can't really say I passed for sure.

I went with regular. Got home and looked at the box and it was 2 oz. Enough to go above the line and some for the toilet.

I think the large would be wise to be on the safe side. I'd recommend a cheap digital thermometer from Wally world to check your shit before you go in, just bring your hand warmer in with you haha wtf was I thinking
