My Cannondale Bad Boy 700 came with a Fizik Pave saddle, which wasnt very comfy so I added a Gel seat cover from Decathlon which helped, however nowadays it has got a bit shiny and with wearing Lycra which is also fairly shiny and low friction I have a delicate problem, I bascially find myself adjusting all the time as it tends to cause my cheeks to slide apart 
Apologies for the mental image, any ideas as to how to improve the situation !
