I was in 40D in February on the Super High-J. I'm 6-foot and didn't find the legroom restrictive. And I could stretch my legs a good deal (although not quite fully) before touching the bulkhead. As with all bulkhead seats, you get much better knee-room, but lose the ability to fully stretch out under the seat in front of you. Not really a problem for me, as my usual LH Y routine is to watch a box-set with a walk/stretch at the back of the plane between episodes Still, good seats, I'd recommend them.
