THE BRP is worth the ride- no trucks 45mph for the most part and that is ample fast considering a 5-9mph overage is pretty safe) and not too many rangers overall. Just watch out in the areas where the speed limit drops to 35mph (usually not far but those are the hot spots).
The Skyline Dr the 110 miles of park roads due north of the BRP while a beautiful ride is only 35mph and some 25mph and more heavily patrolled. Beautiful on a clear day but the low speed will wear you out - a radar detector would be a good purchase for that stretch of road.
If you are set on west east/east west - but the BRP is hard to beat imo especially if you haven't ridden it before - here are some other roads you may like.
211 two sets of ranges to cross
250 is nice,
56 is a good ride
60 isn't bad
