I'd say the majority of holes tend to favor a RHBH player because the majority of players predominantly throw RHBH. But I don't think that necessarily means holes finish to the right of the "fairway" so much as lines required to get to targets favor RHBH regardless of if the hole actually finishes left, right, or straightaway.
In my experience, holes that finish to the right tend to have softer turns that allow for a RHBH turnover or anhyzer shot to get to the target, whereas some (but by no means all) holes that finish to the left tend to be more closed off to a LHBH turnover or anhyzer approach. Dogleg and hairpin turns in fairways tend to be much sharper/tighter when going from right to left than from left to right. I know I've played enough holes that turn or finish left (strongly favoring a RHBH) that I've never seen the equal of in reverse. And when I have, they've been highly criticized holes.
Funny thing is no one ever comments on a hole or course being a "righty course" or a "righty friendly course". No one ever describes a hole as a/the "righty hole". But you hear "lefty" and "lefty friendly" used to describe an awful lot of holes and/or courses. Every course I've ever played that was referred to as a "lefty course" or a "lefty friendly course" usually only has 3-4 holes at most that in any way favor a LHBH or good RHFH...some only have one.
It's all good though...just adds to the challenge. Nothing better than beating a good righty hole as a lefty.
