I see that you've tried the Lady Gel Flow, but what about the SLR Lady Gel Flow? It's firmer than the regular Lady Gel Flow, but not as firm as the Glamour Aspide (which I loved except for its rock-hardness at 40+ miles). IMO, the shape is about the same between the Glamour Aspide and the SLR Lady Gel Flow.

I really want to try the Turbomatic, but I'm afraid that the dome would be a dealbreaker for me
