I think that it would be a great deal for the Moto Ti frame.
The Lynskey Helix is MUCH stiffer than the MB frame.
I think the ride quality of the MB is excellent. It is very smooth and takes the bumps out of the road. I had the one with Ultegra. This was before they offered SRAM on them. I liked the bike alot and it made me realize how nice MB bikes are for the money.
I have always coveted a Lynskey and when they were selling the demo frame I jumped at the chance.
They have similar geometry but like I said before the Lynksey is much stiffer.
