Well, I presumed that this should be a lead directing double, although iy could really be a plain penalty. So, if it is plain penalty it probably doesn't matter much what I lead as they are always going down. If this is a LD double what lead it suggests? We bid three suits. Pard already bid 1♠ to show some values so double probably shouldn't be spade oriented. Now, what concerns me is: did partner double to tell me please lead anything but spades? Or did he try to send some message about what suit to lead? I reasoned like this: As I managed to show my two suiter pards double is probably oriented on one of my suits and not on spades. As he couldn't support my clubs because of 3♦ bid by LHO, and he could support my hearts it seems to me that normal lead from my hand would be the ten of clubs. So if my partner wants me to lead a heart (because he has doubleton honor or something) then he has to either support my nonvul bid with doubleton to show the lead, and I don't like that approach, or he can double 3NT to suggest a heart lead. I'm not sure my reasoning is good so I would like to hear why. ;)
