I will discuss how the theoretical stability of exclusive HVM photoproduction has been improved through a systematic taming of the known MSbar coefficient functions by accounting for a not so power suppressed correction encoded within a ‘Q0’ cut. The phenomenological implications of this will be emphasised allowing for, ultimately, the inclusion of the exclusive data into a global fitter framework to provide constraints on the small x gluon. Time permitting, I will also present preliminary results for exclusive HVM electroproduction.
