To avoid that scenario you just need to make sure you have an open GCD for whenever Rend ticks or MS comes off of CD, I use pastebin.com/LhS2eU3W (WeakAura) to track my Rend. Whilst Archi is <20% you should only swap to the infernals to put a Rend on them if they're going to live long enough, then just cleave Executes onto them. Your Reck CD with AM is about 2 minutes 10 so you're always going to have enough time to pop it on pull unless you've got some crazy DPS going on.
