Yeah, I dunno if 50% would be an appropriate ratio myself. If you would need to lower frequency, you can flat call if the lowest ranked card is of a particular suit (suits). As an example, you'd call 2c3h7s, but 3 bet things like 2h3d7s, 2d3c7s, and 2s3h7c.
Using suits isn't a bad idea to balance 3 betting/calling 2cd draws since suits rarely matter in this game (as long as you avoid flushes). Also in my quick addendum, I also point out how the numbers change if you are 3 betting pairs of your 2cd draw like 2447. Given a 2 cd draw, you'll have a paired card to go with it almost a third of the time. So 3 betting 2 cd draws with pairs only and calling all others is probably a reasonable frequency, and the hands themselves are slightly stronger, which is never a bad thing when 3-betting.
But like you say, I'm not totally convinced a mixed strategy of calling/3-betting 2cd draws is best. The amount of HU play I have is minimal. But I would suggest, if one uses a mixed strategy, to avoid 3 betting based on hand strength only, like always 3-betting 237 and always calling 368.
Also I wouldn't use mono suit to snow decent 2 cd draws though...I would save that for gutshot straight and flush draws like 8654 suited.
