On a very rainy day, (they closed the park and water was coming over the perimeter road) I attempted Doubletop from the South in the 2000's. The walk over the beaver dam was under calf deep water and as other's mentioned it was steep. I go stopped when, what should have been a simple brook crossing was a raging torrent that would have required a step onto a rock I could make out under a few inches of quick moving water. (To put this in perspective this was in roughly the same time I did Owl's Head when the 2007 NH flooding occurred and the crossing was thigh deep and dumb to do.) The water moving quickly, in part due to the amount and steepness of the terrain.
Doubletop and The Owl remain as my needs to do also on a BSP trip yet to be planned.
