For what it's worth......
I run a 15/52 off road on my 04 fe550. First is a rock crawler, should be good for bunny hopping the logs, and 6th tops out at 100mph exactly.
That gearing is very close, just very slightly lower, as 14/48, which from general observation, many of us run on the 550.
I don't have any chain slider wear issues with the 14T, and a 52T sprocket would require a longer chain, so for me it is a bit easier to just go with the smaller CS sprocket.
I do agree that this final gearing is just right for the 550.
