True dragonbone would pack more of a punch, but this build is about speed, not overpowering opponents. Crossbows are slow, but the stagger is too good to pass up plus an opening exploding bolt is a lot of fun. Zephyr goes with the roleplay. Speedy bow for a speedy archer. Doesnt mean you gotta do what I say though!

Dragonbone bows are actually relatively fast: they have a speed of 0.75, which is the same as a normal Dwarven bow (but they have 2x the base damage).  Zephyr is still faster -- as fast as a standard Long Bow by my reckoning -- but it's not a huge difference, and I think with Quick Draw + Steady Hand it'd be more than fast enough for the build.  And since it does 2x as much damage as Zephyr, it should make battles quicker.

Very nice build +1 I hope I see more builds by you!

Not really.  Like I already said, you can just swap out the perk points from Alchemy, and the training comes from natural gameplay: just run through a few Dwemer ruins with a follower, collecting all the Dwemer scrap you can.  Most Dwemer ruins already have associated quests, so you'll enter them through the course of natural gameplay.  Once you've done a few dungeon dives, you could have the equivalent of 300+ ingots, which is way more than enough to go from 60 (Arcane Blacksmith, already in the build) to 100 (Dragon Smithing) on Dwarven Bows.  Hell, I bet that's enough to go from 30 straight to 100.  Since you need to go from 30 to 60 anyway, you might as well just collect enough to go straight through to 100.  You really don't have to go out of your way at all to make it work.

You are awesome! Thanks!

Zephyr is not 20% faster than any other bow; in fact it's actually slightly slower than the long bow.  The long bow has a speed of 1.00, whereas Zephyr is 0.75 + 30%, or 0.975.  The Dragonbone bow is a bit slower at 0.75 (same speed as a normal Dwemer bow) but also does 2x the damage of Zephyr.  Thus, Dragonbone bows have significantly higher DPS than Zephyr: ~15 vs ~11.  See the Archery page on UESP for reference on this information.

I haven't personally gone to 100 Smithing on any character, but that's only because I've never had a character that was well suited to Dragon armor/weapons, so it seemed superfluous.  With the Warrior perk + Rested, it shouldn't take more than a few hundred Dwemer ingots to go from 30 Smithing to 100.  This build already calls for 60, so again, why not just run through one or two extra ruins and collect enough scrap to go all the way to 100?  If you smith them all in Riften, you can sell them to Balimund and pay for training in between each set.  I bet it would only take about 2-3 Dwemer dungeon dives with a follower to get the materials, if you also train.  And again, you're probably already going to be dungeon diving, so you don't even have to go out of your way to get the materials.

I disagree with the notions that it may be tedious or out of character, for the reasons that I've now stated multiple times.  If you disagree, that's fine, but it doesn't seem to me like anyone has actually refuted my points very well.  At any rate, I'll say again: this is a great build, and whether or not my suggestions are taken into account by anyone seeking to play it, it should be great fun.

In my experience, UESP is always more reliable than TES wiki when it comes to any mathematical matters.  The Archery page on UESP has a graph that shows bow damage per second.  It lists Dragonbone as 15 dps, and a note below the chart listing Zephyr as 11.7 dps.  On the Unique Items page, Zephyr is noted to be 30% faster than a standard bow.  Standard Dwarven bows have a speed of 0.75 (again, see the Archery page).  Based on the formula (see the comments on the Archery page) my math seems to check out in terms of setting the speed for Zephyr at 0.975, which is slower than the Long Bow's speed of 1.00 (though of course, Zephyr has higher base damage).

I am not disputing that Zephyr would be an effective bow for this build, I am merely positing that the 2x power and 3.3 higher dps on the Dragonbone bow would more than offset the slightly slower draw speed, especially when combined with Steady Hand and Quick Draw.  The draw time difference would be about 0.1 seconds, which IMO is negligible.  Granted, I haven't play tested the build, so again this is just speculation on my part.  I am confident that the numbers on UESP are correct though, so the theory behind the speculation checks out.  Granted, due to the discrepancy between the two wikis, it would take someone with access to the console (and a fair understanding of how it works) to truly settle the question.

Ultimately I'm sure both bows would work just fine, I don't mean to make a mountain out of a mole hill.  It just seemed like an option worth some cosnideration.
