Eviscerate would be doing 4913.02 damage on average with 15% mitigation from armor. Both are assume to have their improvement talents for 20% and 15% increases to damage respectively. Rupture would be scaling better with AP in the same situation, although if mitigation from armor goes to 0%, then Evis would become better for scaling. If both Trauma and Mangle are available instead of only one, rupture will be better on a per finisher basis.

For the 47% base crit rate, that gives us a 53% crit rate with Evis, and results in an average of 68% of your finishers being Eviscerate. Throwing that in, we get 3340.85 average damage per finisher using Evis, vs 2168.09 average damage per finisher using Rupture. At that point, even with both Mangle and Trauma active and a 15% damage mitigation from armor, Evis will be the better finisher, resulting in using Evis and CttC better than Rupture without CttC, though specs could change that.

Since getting CttC and the necessary support talents forces us to not get DW spec, CttC 58/8/5 should be a reasonable spec. Using two 115 DPS, 1.7 speed daggers, we get average mutilates of 3929.31, assuming 15% armor mitigation and FW up for both. We get 1.09s swing times, with no haste rating, expertise cap, and a 19% miss rate with no hit rating beyond what is needed for specials. This gives 885.49 DPS from autoattacks. Poison damage would be hard to calculate without knowing level 80 poison values, but since most mutilate specs should have the same poison DPS, I'm not going to worry about them.

Now, I need to calculate the value of FW for this build. Assuming you pool energy before using S&D, your next evis will occur during FW. However, if you are trying to get FW on that evis, you can't pool energy to allow your next finisher to benefit from FW. As such, the number of eviscerates affected by FW will be equivalent to the number of S&D's you are forced to use. As FW has no affect on S&D, the uptime for FW should be .32/.68 = 47.1%. This increases the average finisher damage to 3498.07. Now, I'm not entirely sure if it is possible to get 2 eviscerates in under FW per S&D, or how often that might occur, so I'm going to assume it doesn't happen. If so, it increases damage slightly, but I'm not sure how to figure out how much FW uptime it would give.

So, with Focused Attacks, I get 10.776 energy regen per second, 6.48 energy cost per finisher, and 117.77 energy cost for 2 mutilates. That results in an 11.53 second cycle. That results in 984.97 DPS for specials. For a total of 1870.46 basic DPS, plus whatever poisons gives.

Now, I'm assuming that you aren't using HfB with the above numbers. If you are, the cycle goes to almost 15.98 seconds, which means you'll be losing some S&D uptime or need more crit or have to drop to 1.6 second daggers or something and you lose FW on finishers due to pooling issues. Either way, assuming you don't lose S&D, your special attack DPS ends up at 700.84. Adding in the 15% bonus damage, you get 1824.28 basic DPS, plus 115% of poisons.

Okay, now assuming we go back to the rupture cycle, we get Non-CttC 45/21/5 as a possible spec. Same poison talents, of course. Again, two 115 DPS, 1.7 speed daggers, we get average mutilates of 4400.81 damage. Our average DPS from autoattacks with the same stats as above is 1033.08. All the damaging finishers will benefit from FW, so the average finisher damage is 2384.90. With 12 seconds between finishers, average DPS from specials ends up being 932.21, giving a total 1965.29 basic DPS, plus poisons.

Now, I suggested my cycle build, I might as well run the numbers for it. Using the same stats and the CttC build above gives me ~95% S&D uptime (and also 95% of finishers are evis), 839.29 DPS from autoattacks with 3929.31 average mutilate damage, 4056.22 average finisher damage, and 7.09 seconds per finisher, all affected by FW, for a total of 1126.31 DPS from specials. That results in 1965.60 basic DPS plus poisons. I can't see HfB being useful, since S&D uptime would drop a ton. So, I'm not going to bother with that calculation.

Both builds with HfB will improve considerably if HfB can be used for free, of course.

Edit: I did not account for FW applying to finishers, because I'm not sure of the percent of finishers which will occur while FW is up. With the current Mutilate cycle, all damaging finishers occur while FW is up. With CttC, I think Vulajin's proposed cycle (the first one, plus the HfB variation, maybe) will have a percent uptime for FW equal to the percent of finishers that are S&D, as being forced to use S&D will allow you to pool energy before using your finisher, so you can get the next evis off during the FW buff. For the final two cycles I did calculations for, FW should apply to all the finishers. I think that might result in a cycle that doesn't actually focus on keeping S&D uptime at 100%, which is counter to current DPS practices. I also forgot to factor in manual refreshes of S&D for the 4th cycle.

I've now added in those things to the best of my ability.
