Hi Bonnie, welcome to TE and congratulations on your weight loss and riding habit!
Since you mention that you're still having some saddle issues even with the Liberator, I thought I'd point out that I noticed from your bike photo that your saddle is slanted down quite a bit. That would tend to put more pressure on your front girlie bits (and less on the sitbones). It also can cause you to put a disproportionate amount of weight on your arms, which might result in shoulder, neck, or hand pain. Perhaps you're fine with this saddle setup, but I just thought I'd point it out in case you were unaware of it. Might want to get out a level, get that seat nice and flat and give it a whirl!
Enjoy riding, and again, welcome to the Team!
Emily
