In that case, keep pulling sumo. It'll help you off the floor with your conventional, or at least that has been my experience. Throw in some conventional deficit pulls as well.
Probably the biggest thing is to lot how often you go heavy. Arguably the best way is to use a training max to calculate your percentages (TM is 85-90% of your max); or if you don't use percentages rarely go beyond 8 RPE (which would mean you have two clean reps left), and only occasionally go to 9 RPE.
