The best #11 cap IMO is the Dynamite Noble RWS 1075. After that I like the CCI Magnum (not the standard) #11 cap. And if forced to I will shoot the Remington Caps. The RWS are just a great cap, hands down. When I use them I seldom if ever have any problems.

A good 209 Primer is the Winchester W209 and the Remington Kleenbore Primer. Stay away from the Winchester WML 209. They are really a hot powerful primer. I never had the pleasure of the new Winchester Triple Se7en primers. If I shoot pellets I use the W209 primers. If I shoot loose I use the Remington Kleenbore Primers.
