Oh yeah, I should have mentioned if you're worried about using Fester right after your opening Tri-D and that it might hit before the DOTs are applied you could toss in another R2 after Tri-D. After the R2, if you give it until the GCD is about halfway recovered before tossing Fester you should have plenty of time to ensure you've got your DOTs on. That is, if you're planning on doing the full three Festers at open rather than the quick DWT method.
