Zap: Yes, easy whistles may be a factor, but I expect a clean slow game. Perhaps not ultra-defensive. I don't see a track meet. I overbet it with intention of selling some back for a middle, so that's what I'll do. Halftime is a good idea also. It still looks too easy, but I'll have what I wanted on under and possible bonus with middle.
The problem with the half is if H1 scores low, then H2 total gets inflated high, reducing middle shot. I sometimes even bet H2 under in these situations ( esp. if fav leads good). I couldn't risk that here, as I have mucho under already.
