You answered the question yourself when you said "through scattered trees"
Rollers are verticle, air shots are horizontal. Verticle discs fit better between scattered trees than horizontal discs.
The spaces between the scattered trees are a least a dozen feet wide. I've seen many a dozen recreational player park the B and C pins on this hole. I don't know of any online pictures of this hole, but trust me, there is little reason for a 1000-rated player to throw a roller when a 150-foot airshot to the A-pin would easily suffice.
