I have been reading more and more that BJ APs are playing 2 hands off the top of a new shuffle. Being that 85% of my play is done heads up on a shoe game, what would be the benefit of going to 2 hands?

Does playing two hands in + RC all the way to TC-2 (wong out) essentially give you 2x more HPH?
Does playing 2 hands help you reach n0 2x faster?
Does playing 2 hands double RoR?
If I were to start playing 2 hands in the beginning of a shoe, what can I expect over the next few thousand hours of play compared to 1 hand?
If I consider playing 2 hands; would I switch to 1 hand in > +2 TC to save all the 10-A cards for one hand and get 50% of the cards distributed, or would I stay with 2 hands and continue to get 66% of the cards distributed? If I stay with 2 hands I'd be running through the +TCs much faster than I would be playing heads up. Does it make sense to stay at 2 hands considering the fact that dealers win more hands in +TCs..


Thanks,
