I have run the exact opposite of what your talking about here. I run a Ti can and arm with a Kr endbell and the performance was/is awesome which I got from Team Br00d here in Washington.
Team Br00d has great motors and alot to choose from. Their website is getting close to being done and you will be able to see what products they have. In the meantime you can contact them at firstname.lastname@example.org
and ask questions and put in an order. Eddie and his team are some of the best motor builders and tuners around and I highly recommend them to you.
