In reply to Mark Haward:
I live in England.
I still cant decide if a July ascent would be better than a September assent.
September definitely seems to be the time when the recession of snow has peaked (in the lower Alpine mountains anyway) - July there seems to be snow that's still melting from the Spring...
Exposed routes I've done which I can manage reasonably well without equipment (psychologically speaking) are:
Helvellyn via striding edge
Tryfan - North Face
I thick Crib Goch looks more intimidating than a lot of the Alpine ridges I've seen in videos.
From this limited amout of info, I'd actually prefer to be on Les Bosses than Crib Goch.
I'd go as far to say that I don't think I'd ever want to do Crib Goch as the terrain is too rocky/jagged.
One thing is for sure, I do feel more secure walking on snowy terrain than crawling up and down
jagged rocky ridges. Even if it's a false sense of security, the main thing is the psychological aspect of exposure. I find the snow provides a more level surface and something to stick my crampons into.
I have minimal Alpine experience - I attempted Hoher Goll (Germany) 4 weeks ago via the Manlgrat ridge.
The first 1500m there were sections of 40 degree slopes where I was "crabbing" across the hard snow with my ice axe, digging my crampons in. I was slightly nervous, but it was managable.
I had rope, harnesses, kit etc, - At 1,800/1,900m, the via ferrate cables were under snow, so we decided to turn around.
