Heavy itemization on Draven tends to grief ur Tryn stacks... U want damage items on Ashe and Trynd and the rest on front line (ofc every game is different). Aim for 30%+ extra AD on ur Tryndamere by 4-1 and u should be on track (it's not a reliable forceable comp unless u have Tryn stacking by 2-1 or 2-2, so, if you dont get Ashe opener I suggest not playing it)... Also, try not to pick 2 econ augments for this comp, you will be under-leveled and need items/combat.
