DinDIP, I actually do play a weak opening system. So I am interested, as you, in other bridge minds seeing this problem and what they suggest for solution. I use double as "misfit expected suit" -- here spades. Cheapest of transfer/NT maybe for hearts if they are unclaimed --may later also show spades. Here I use 4D=pick major. In 4M on half the deck -- but pure, nothing in their suit.
