After 950m you go below 30meter, that isn’t soon. You might think about saint sauveur, after 200meter you reach 70meter.
But yes contact Oli, conditions aren’t great atm but he knows where to go.
Cabouy and St. George drop straight to 30 meters at the entrance. Then you go up again to a depth of about 20 meters. For me as GUE cave 1 diver they where fun to dive but with these depths you can reach turn pressure pretty fast.
Landenouse is not too deep and a great cave to visit in my opinion. In Ressel we where limited to the point where we reached the second T (soon after the drop follows anyway) but that is not the case in Landenouse. These caves are also not too far apart so can be visited on the same day.
