You might not need or get any benefit from the chamois or faux-chamois padding, if your saddle is comfortable now. Padding might even cause problems -- more perspiration absorbed, more chafing, etc.
I switched from padded shorts this summer after chafing from soggy chamois. Switched to Champion boxer shorts, same wicking fabric but thinner, under baggy shorts. More comfortable for me.
If I rode fast enough for wind resistance to be a factor I'd look for tight cycling shorts with the thinnest possible chamois. Only reason I might consider thicker chamois is to compensate for an unyielding leather saddle that wasn't broken in yet.
