2.5 deg/min. is a little slow. Try and aim for 10-12 deg/min. The lower the rate of rise the more viscous the resin which means it won't flow as much. Also, try going into full pressure right away. This will also force the resin to flow. I've found kiss cycles don't buy you much plus the operator might forget to go into full pressure before the resin starts to cure (if you're press doesn't do it automatically). Double check your vacuum pressure. You should have at least 27 in. Hg.
