I have been useing bare fisted in primary but useing redcap claws in the secondary (+6str) and i tend to get a little more dps that way at 22.

I am a lvl 17 monk (drunken style), and I got one nice handwrap (18dps), and one decent knuckles (12.5dps).

Unarmed: 38.50 main hand, 19.25 extra dps off hand.

18dps hand wrap: 58.00 main hand, 12.00 extra dps off hand.

both handwrap and knuckles: 53.78dps main hand, 18.84 extra dps off hand.

11.67dps windblade: 51.75dps two handed.

A few things which I noticed:
- With a good handwrap/knuckles/ulak/claw you can get significantly more damage. From 38ish dps to 58 is a lot!

- When you have a better weapon on your main hand, your off hand dps drops. When I am only using my main handwrap, I get lower dps on my off hand! This is probably because of the difference between your main hand weapon, and your off hand weapon. When I used two identical claws, I also had a DPS drop, but when I equiped both of them, the dps loss compared to both unarmed was gone, I actually gained a little! Both claws were weaker than my knuckle which I use on my off hand. My main hand had a lot less dps, but my off hand was better!
So the best is to have two identical, or similar weapons in both hands. I can't imagine the dps boost I would get when I would have two 18dps handwraps!

- My windblade, which has far less dps than my main handwrap, or my off hand knuckle still has some good dps! The difference is not really minor, but with a 15dps windblade I would be better off than now! I used to have a 16dps staff which I gave to a guildmate because I bought the 18dps handwrap, but I would probably be better with the staff. (It also had +25dex). This shows that for tanking (windblades are better for tanking as they have some % parry), you do not have to lose a lot of DPS.

Just my two cents, hope it's useful to some of you.
