I think it's more appropriate to put Crucifix in the trilogy instead of the Rostrum. Even though they both got the 11c rating, Freestone and the Rostrum couldn't be more different.
The climbing on Freestone is good for sure, bottom half is the silent line style grooves out on a clean wall. Fun and unique stuff. Top half is the burly corner system. Honestly though, the climbing has got to be better on the Rostrum, and Astroman too.
But... for one, there's the adventure factor.. Astroman barely makes the cut in this regard. Rostrum is cragging. Crucifix is in there. And Freestone is OUT there. 1 bolt on the whole thing? With a solid amount of face climbing too
And, of course, as has been said, location location location... FS takes the cake.
