mont blanc from tete rousse?

[owenel]

i've been corresponding with a guide in france who is suggesting we do mont blanc summit attempt from tete rousse instead of gouter due to unlikely availability of space in gouter. what i'm wondering is whether the shorter summit day would outweigh the drawbacks of camping near gouter. my understanding is that a summit day from tete rousse is 5700ft in elevation gain. i personally have never done more than 4000 ft in one day, so a little worried about trying it on what will also be my highest altitude climb. anyone have insights about this? i'm also considering bailing on the mont blanc climb this year and doing monch/jungfrau instead.
