It depends on what kind of sound signature you prefer and what kind of music you listen. CSA, T2, T2 Pro are close to neutral and somewhat bass light. TFZ T2 are warm sounding (I personally haven't heard them but that's what the general consensus is) And CCA and Lark are proper V-shaped IEMs which are very much inline with your recent purchases.
If you want V-shaped stuff then Lark and both CCA are very good options. If you want something close to neutral then Tin T2/Pro/Plus are good options although all the iterations sound great albeit with some minor kinks.
I listen to blues/rock mostly. I like there to be meat on the bones of the music...that is an easy way to put it that most people understand.
