I'm an xxxx balancer myself, and I am with those who are not (overly) worried about double on my left. These guys are at favourable, and LHO didn't make a gametry. The odds of his having a 2 trick set of my balancing 3
♥ opposite a white v red (and therefore potentially awful) 2
♦ are very low.... compared to the chances that we have a game, they are insignificant. And it would be a brave (foolhardy?) opp who doubled me for a 1 trick set. If I'm getting doubled, it is probably after partner stretches to raise.. now the double is less costly when wrong, so more likely to be made for a 1 trick set.
Note to Keylime: hyperactivity in direct seat is a poor approach... but I suppose it depends on what you call hyperactivity

When you come in with wide-range overcalls, as you must if your lower limit is 'hyperactive', you place far too much pressure on partner, who has limited bidding space in which to find out how weak you are. Better to be relatively conservative (Hannie posted a good low-end overcall hand earlier), so partner can participate meaningfully.
