The dynamic compliance of AT33PTG as stated is ：10×10－6cm/dyne（100Hz）. Using this cart with your AS-309S, compliance should not be the major issue.
For highly rigid TT and Ortofon arms, some more attentions need to be paid to the supporting platform which helps eliminate harmful low frequency resonance as much as possible during loud passages. It may take some time to tweak according to your taste and preference. You may look for clean, high transparency, tight bass but NOT super warm, tubey but booming bass, soft tender extra sweet sounding...pls correct me if I am wrong. BTW, what phono amp will your cart be hooked up with?
IME, AS-309s is "relatively neutral" when comparing to other popular models on the markets, you gonna hear more sonic signatures from your cart and phono amp. The basic approach to begin with AS-309s is to find a high quality cart(I would prefer LOMCs in your system) according to the recommended total cart weight with headshell(i.e.18-25g for standard counterweight, 26-38g for optional one).
I like some carts made by Shelter, Ortofon, Dynavector, ZYX but unfortunately they are not on your list.
Good luck and VBR
