Transform Feedback with offset

I have a transform feedback setup, which is working correctly. It has an input of say 1000 Vertices and feedbacks the same number of vertices.

http://prideout.net/blog/?p=67 is the reference for our implementation. Now as part of optimisation i need to limit the feedback vertex count with an offset. Means i should be able to render the last 500 vertices and feedback it to location 500 - 1000 in the feedback buffer. We thought about having multiple VBO setup but we think its could be a performance hit, since we need to keep changing the bind buffer. Please sugggest best way to accomplish this .

By having multiple buffer object setups. Performance hit or no, that's how it's done.
