thatsplenty quick enouph IMHO what kind of arrow do you shoot!
I got a Bowtech Defender this year also an 05 model I like it a lot, but I dont think its any better than my ViperTech and ViseVersa so far I shoot both equally well. I dont think you are behind times with your ViperTech, because its out of production, I think the Trykon is the big hype right now with the parallel limbs (or ever how you spell it)lol. I thinkthe vipertechwas the most parallel design they had untill now.
Other than getting bored and just wanting a backup bow is the only reason that I got the bowtech although it is nice.lol
