First congrats on the Civic, very nice cars
As for clay, it's so odd that all I use is Ricardo clay bar that I haven't used anything else....I've never used the PB clay bars so don't know what else to recomend. Oh I've tried the Meg's regular clay bar (white clay bar) dosen't have a bite and I found it to be very mild and wasen't very good for my taste...any who ever since then I've used Ricardo and haven't had the need to change if I need a more aggresive clay I'll use the Red Clay Magic.
Well that's just me hope this helps
