Below is a pic of the Santa Ana Road suit pad. It works for me. I have no complaints. This was last years so to be honest I’m not 100% sure if they are using the same pad in 2019. Web site didn’t have any pixors which always makes it a little harder to decide…I’m 5’10" 165# and this is a medium. Pad fits and sits well for me.
Below is a pic of a pad similar to the Rincon Bibs I had some years ago. One of the original owners had me test them out but, I’m not sure if they still make this bib. The Hollywood had the same pad. Anyways, this pad is very nice and is very similar to Vie13 which is another kick ass brand. IIRC the higher end Castelli has this pad in it as well. So not sure which Castelli bib you had but, their Kiss pad sux compared to this one IME.
