Recent large scale structure observations, including COBE, have prompted manyauthors to discuss modifications of the standard Cold Dark Matter model. Two ofthese, a tilted spectrum and a gravitational wave contribution to COBE, are atsome level demanded by theory under the usual assumption that inflationgenerates the primeval perturbations. The third, whose motivation comes bycontrast from observation, is the introduction of a component of hot darkmatter to give the Mixed Dark Matter model. We discuss the implication oftaking these modifications together. Should Mixed Dark Matter prove necessary,very strong constraints on inflationary models will ensue.Comment: 10 pages, plus figure available from ARL SUSSEX-AST 93/4-2 LANCS-TH 93/
