I've had a DAS Master Hunter with Winex limbs since March. And near as I can remember looking at my log, I've put around 10k shots through it. It's a nice bow and shoots well, but it's no speed demon. Truth be known, it shoots the same speed as any of the Chek-Mate recurves I've ever owned, as well as my homemade recurves. It's a bit slower than my old Palmer double carbon and my Thunderstick MOAB longbow.
The main reason I bought it was because I could get extra limbs for it pretty much anywhere, cheap and with no wait. With replacement limbs for most custom bows running $500 or so and taking 6 months-plus to get, that advantage was huge to me.
I can't say it's extended my effective range as a bowhunter because, quite honestly, my "effective range" is already a lot further than I'd shoot animals anyway. If you really think you need a new bow to extend your range, my honest advice would be to practice more with what you currently have. That's not meant as an insult, by the way, just one of those "been there, done that" sort of things.
