Realistically, EOD will be good enough that you should not have to inject prop in between. I like to run prop ED, that is why I would suggest using it. This is a very minor point. As long as you don't go past EOD with your injects, you will be fine.
On the other hand, if you decided to go 250mg E3D, you would need to substitute the prop on those other days. In that case, run 40mg of prop ED (on the days you inject sust...leave off the prop). I have been reading about this, but again...I have never used sust. I know that TheSeventhWarrior has, and he subs in prop. Catch him online, and PM about it. I expect that we would be telling you about the same thing, but I would prefer getting advice from someone who has actually tried something like this.
