poor shifting from small to large
If you're comparing with Shimano rings, you either have to get used to poor front upshifts or buy a Shimano chainset. If you want Shimano rings on your Z cranks, I think FC-6650/FC-5750/FC-4650 are the last 5×110mm sets with flat rings which will fit, you may still find NOS spare rings relatively easily, or even a complete chainset for the same or lower cost. The Tiagra ones are even a decent visual match for the Z rings🙂
I always used praxis and I’m happy with them. But I think they are rebranded as look ones. Why do you not like them?
