thanks girls for your input...

the way i had to set my saddle was with the nose lowered down a couple of millimiters lower than what it should be... because with a raised nose, it hurts even more... so for me that's not an option.

i find myself more in line with the way alpinerabbit described her riding, although in my case, the green dot i think is placed further down.

today, i called the SMP headquarters to understand better how one should be properly sat on the smp's....
apparently both bones (ischial and sit bones) should be resting on the saddle, meaning sitting on the 'flat' part.
then ofcourse one moves around the saddle a bit, but at least the sit bones shouldn't rest on the side/sloped back area.

and i think this is my problem, my sitbones in a sitting position are 130mm wide, when the glider is 136... they're basically not sitting on the flat part.
i'll test it out tomorrow again and see exactly what happens.
maybe upgrading to a wider smp saddle, positioning-pain-pedal stroke will be improved.

thanks a million for your feedback!!
