Help saddle problem tri to road

Hi
Search the forum and learned a lot
I would like to know if any of you have passed or can guide me
Spend a lot of time on a bike with an adamo attack
Very comfortable in tri stance
Now build a route bike and put the adamo attack, and I’m not comfortable
It brings me like pain in the buttocks and bones of the tail.
Another thing that sure is the posture, fatigue in muscles that in the triathlete did not happen to me.

I was thinking of some
It has a channel for the soft parts that adds a lot.
Thank you

P.D sorry my english
