I'm shooting those DAS longbow limbs I got off of you Mike. Super quiet so far. Can't tell you much about the speed as I have not come up with the "arrow" yet. I can tell you that the full menu of arrows I ran thru it impacted pretty nicely on the target.
As far as Trad Tech 2.0's I have never had any issues and I have had a couple sets. Save your money in the difference of the carbon/wood over the glass/wood though, not any great gain there except in dollars spent. If you jump to the carbon extremes that is another story.
Good Shooting->->->->Craig
