With a partial Siberian snake in the AGS and transport lines with interspersed horizontal and vertical bends, the incoming spin direction at the injection points of both the collider rings is not likely to match the ideal vertical stable spin direction of RHIC which has two full helical Siberian snakes per ring. In this paper we examine the matching of a polarized beam transfered from the AGS into RHIC. The present 5&percent; partial solenoidal snake as well as a proposed 20&percent; superconducting helical are considered for the AGS. Solutions with retuned snakes in RHIC to better match the incoming beam have been found. © 2003 American Institute of Physics
