I used option B on my Hobie 18 for years, and liked it.

I used option A on Hobie 20, and now on my 6.0.

I really like option A better, mostly because in light air when the crew needs to go forward to the lee hull it's one less thing to crawl through/around/avoid entanglement on...

Of course, on the 18, having the rotation limiter where it is probably meant the option B route would be the only one to work to avoid getting caught there - that happened all the time before I added the preventers.
