I agree with smerriman that 4♣ would help involve partner in this decision which, from your perspective, is highly likely to arise.
I also agree with Marlowe that we should not be sacrificing at red vs green. This is a losing strategy so bidding 5♥ should be to make.
In an expert bidding panel, double always wins these polls. It is seen as the most flexible action, but in reality only allows partner to bid if they've misbid earlier.
Here I think double is probably right. They are not making an overtrick and it is not the end of the world if they make 4♠ doubled; whereas losing -500 in 5♥ may be.
The opponents bidding would be more interesting in an expert forum: the 3♠ is normally just competing, not a game try, and the 4♠ bid rare.
Finally, as I've said before, only David Burn gets these right all the time:
- The five-level belongs to the opponents
- When in doubt, bid one more
- Choose the correct option
