Today I was on both, first red then blue. Red very interesting, entry morning a bit slippery as wall damp and somewhat muddy (shoe deposit), rest super, recommend full finger gloves as got quite a few blisters, via ferrata set handy too.
Blue comparable to Lisco, just bit more muddy.
For both dry weather recommended as approach has wet ground.
Descent under power line could be problematic wet, very steep and path already very slippery.
Red took me 50 min, blue 20 min, each knows own time, caution is never excessive.
