I carry an F-103 and and an F-105. I've almost always been using the 105 on Toulan. It might have had a couple of tiers worth of depth enhancers at the time, but they've all broken while I've been and I wasn't really paying much attention at the time, so I can't be sure. It was right before I stopped exploring and just concentrated on trying to meet Aqeeq, Sham, and Youd demand.
Now I'm back to exploring again and I've got most stuff sorted out, but Qasdeer is proving elusive.
I haven't stopped looking.
