  Localization of flux lines to splayed columnar pins is studied. A sine-Gordon
type renormalization group study reveals the existence of a Splay glass phase
and yields an analytic form for the transition temperature into the glass
phase. As an independent test, the $I-V$ characteristics are determined via a
Molecular Dynamics code. The glass transition temperature supports the RG
results convincingly. The full phase diagram of the model is constructed.
