Using multiple TINs in GeoRAS

I am looking to do some hydraulic modeling on some rivers that are over 400 stream miles in length, and will need to use multiple, overlapping TINs.  My question is, does using the multiple TINs approach over a single TIN present disadvantages in GeoRAS?  For example, will a cross section that covers two separate TINs run into elevation issues?

Anyone who has experience in this effort that can provide some guidance would be extremely helpful.  Thanks!
