Let's pretend that I'm writting an essay and I want to start a sentence with phrase "I dare suppose". I know "I dare say", but I think it's incorrect write "say" when I'm writting , so I want to use "suppose" instead of "say". What do you think?
Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.

I dare suppose sounds natural to me.
