One good player that I know says this: When you are playing trumps with a 9 card fit, you cash the A (or K) and an opponent has QJ doubleton... With no information of the opponents, assume that when opponents plays the Q, he is MORE LIKELY to have QJ doubleton, even tho the restricted choice says otherwise. If he plays the J, then you should go for the restricted choice. More and more player will try to fool you this way and the principle of restricted choice is based that with a same opponent presented with this holding x number of times, he will play the Q 1/2 of the time, and the J 1/2 of the time... With humans (especially for those who do not know the restricted choice), this is cleary not the case. So how does it compare to here? Well with J10 holding, you will more likely see the J rather than the 10. So I would just play for the drop and too bad if they were 4-1. But here, I do not believe I would finesse even if I see the 10... I mean it's too easy for opps to play the J or the 10 from J10 holding.
