I've tried both, measuring in at around 150 for my seat bones. The SLR is nice but very padded, and the aspide glamour was super comfy on the seat bones, a lot firmer than the SLR but I got a little smashed in the girly bits. In retrospect I should have adjusted it a little more before selling. I did find almost perfect happiness with the SI max flite. Same measurements and not as squishy as the lady SLR. The cutout is perfect and the saddle is long enough for drop riding with comfort.
