Ok my Habby shows up and beautiful Ti. I got the model with the curved
stays as opposed to straight. I was surprised by the large curves in
chain and seat stays. Looks great have not had a chance to ride it but
any wizards out there give me the dope on curved vs straight stays in
a Titanium frame. Or any other for that matter.

My answer before I read anyone else's:

1) marketing

2) heel, chainring and tire clearance in the case of wavy chainstays.
