Ah, that's fair.
With no positionals since all frontal, the two combos you're looking at are:
HT>IDC4>P>TTT[pop]
100+180+220+(200+200+170+150+200+360)x1.1 = 1908
And:
HT>TTT4>P>TTT[pop]
100+150+200+360+200+170+150+200+360 = 1890
It averages out to be about the same, but the Disembowel also buffs up your PS+Jump, Leg Sweep, and Mercy Stroke (and geirskogul) and CT will tick about 3 times for an additional 105 potency, so I tend to use the CT one, but either is really just fine. One just gives you a bit of an extra edge over the other. I ignored HT and DoTs since that's identical between both.
(You use Phlebotomize because the 4th hit will be 200 potency and Phleb is 170+ticks - 1 tick bumps it over 200)
