1- Drake 900 grams, Dartmouth, Clayton 675 grams
2- Promanade is 550 grams
3- Memoirs RF, 125 grams
Bowl depth is better on the Memoirs and on the Toto Drake, Dartmouth and Clayton.
I've had good success with the G-Max and Powergravity Toto products.
Another one to mention would be the Toto Dalton, good performance and good bowl.
