Hi, I have done the tete Blanche and petite fourche in the last 2 weeks. Although we did the tete Blanche by the north face, so I can't comment on the ridge route, you will pleased to know that the descent is basically non-existent, just a very short, easy snow slope to the glacier du tour (you start at a lower elevation and climb up to just above glacier level). The approach involves a small scramble over the col du tour... Worth leaving Albert 1er as early as 3 to catch the sunrise over Switzerland from the col... Incredible. As for the petite fourche; easy snow climb, not steep or long, but a really cool summit, with a great view over several glacial basins, and a nice spot to sit! The glacier du tour is not very crevassed at all, especially along the left side ( as if ascending) where you will be, so of course be careful, but it isn't too stressful. The summits both have great views, shouldn't be too busy, and the approach/descent aren't too taxing. Enjoy.
