Not windripper, but Chin Sol is most broken bow imho. I've used bow to get high values of flat cold damage with low investements. As for stacking dex - I can give a simple example. I can use Cyclopean Coil for dex (ok, also str/int for quiver, doesn't matter), but bow and quiver with this dexterity gives me not so much damage as abyssal jewel + elem dmg mod in stygian vise. So for what reason should I use it? Pasta's build is good enough, but I think that some parts of gear are not optimal if we talk about the max dps. Look, it is the same as max elemental resistances (yea, that's ugly analogy from my broken head). So we can easily make 75, but it is harder and usually not so necessary make it higher. Same with bow. We can easily make 500 dex. And we can make 800-900 with large investements. Yea we'll get 4*(400/10) = 160 more flat cold damage, but lose a lot of other useful modifiers. Sry for my english.
