The pictures posted here don't look "anything" like the Maverick trapway. The Maverick would be a much better choice then the Summit.Quote:
The Summit 3 is an offshoot of the Maverick and owes its utility to the flattery it gives the Drake employing the 3" flapper and the 2-1/8" glazed trapway.
The Maverick bowl has a trapway similar to the Drake, but not the Summit.
Below is the Maverick bowl which uses the low dip in the trapway to create more siphon, and points the waste down the drain at the last bend.
These two bowls are totally different.
