No more than two or three teams every year as average, the route is almost completely unequipped (maybe three pegs left). The hut book of the Jachia bivy has just 15 pages of entries for the last 15 years...
This has nothing to do with the quality of the route (which is outstanding, one of the best TD of the Alps), but because it's a route regularly excluded by the "best of" lists, and because the access to the Jachia hut is a climb in the climb (no trail no signs and several moves of III)
It's not a dangerous route (the rock is almost everywhere outstanding red/yellow granite once you're in the ridge proper), but it's really exposed in the upper part, and serious as every Jorasses line. Has the great advantage of "no glacial approach", so you need crampons and axes, of course, but you can forget about crevasses until you're on the descent route.
And yes, it's very strenous. 1600 metres of vertical gain from the car park to the hut, and 1000 metre of technical terrain the next day.
It's, most than anything else, a great aesthetic experience on primal "adventure" terrain, but many may find it not their cup of tea, and it's (again) a serious route that requires stamina and experience. Personally, I think that the moonrise light on the three ridge towers, seen from the summit of the Aiguille de Tronchey, it's one mountain image will always remain with me.
There's this great picture by zoom meister Antonio Giani will give you an idea of what I mean

The ridge is the skiline on the right. Just to put this thing in the right scale, the base of the picture is at 3400, the summit at 4100.
Direct route - I've bugged Ugo Manera a lot last autumn to give me the precise trace, but "Pan e Pera" just said "go straight through the centre of each tower". The direct route has been repeated MAYBE two times (go to go at the Jachia again to verify), so you'll not find a lot of pegs either.
