I really like the way you've restructured your guide to account for some of the 'what ifs' and play style preferences. I personally prefer the Evisc route even though you've shown the value of rupture.
I'm not BiS yet but I found the extra haste helped me a lot when I was getting beat by rogues with less ArP and less hit than myself. Breaking down the recount and skada damage I found it was the instant poison procs and extra strikes / sinisters that were causing me to slip down. Gear comparing revealed they had pieces of gear that had haste which I don't have yet. Your adjustments to the recommend crit to aim for makes more sense now than from your original posting.
Despite my preference for Evisc I do look for useful moments to pop a rupture during encounters, specially when I'm going to have to move or fight mechanic is going to yield me incapacitated for a few seconds (PP, BQL fear, BPC pushback from Valanaar's empowered vortex, Saurfang just before beasts pop and I don't have KS or BF CD's etc. etc.).
Very nice job overall with maintaining your guide over time.
