What seems to have a better reliabilty track record, a cable or limb driven rest? Those of you that have had both, whats on your bow now? I know alot is personal preference, but what made you decide ro go that route?
Here's the deal with limb driven technology and how it ties in with the standard mechanical rest:
The time frame from which you first release the string and it begins to accelerate, to the time your arrow detached itself from the string and initiates flight, is known as the "shot cycle".
What a drop away rest is designed to do is provide a resting point, known as the "launch platform", to support the shaft until it rea he's a velocity which it can sustain its own flight, a term known as the point of "self sustainability".
For maximum rest performance, you preferably want your launch platform to remain erect for about 70% plus or minus of the shot cycle, then instantaneously drop in a way which clears the fletching completely, and doesn't bounce back up and contact the fletching. If it stays up too long, your fletching won't clear the launch platform. If it drops prematurely, you experience something called "arrow dip".
Limb driven rests basically offer three guarunteed advantages- because they're operated via your limb and not your cable,
1- They guaruntee an erect platform for the maximum amount of time desired within the shot cycle (a quality drop away is more than capable of doing this)
2- They eliminate the possibility for pulling the lower cam out of time due to incorrect setup since they don't attach to your cable (a quality drop away will never do this if set up properly)
3- They're easier and quicker to install (because proper setup of a drop away needs to be exactly that, a proper setup)
There's nothing wrong with them, but they will not out-perform a good, high quality drop away that's set up correctly. It all comes down to a matter of preference.
I shot the Vapor Trail limb driver for about 3 months, but ended up switching to the QAD HDX, and of which I now have 2, one for each of my bows. When properly set up, I know from experience neither one outperforms each other. I can tell you that the HDX has a mechanism that prevents shelf jumping, and in terms of General quality, there's a reason they're so expensive, they're absolutely gorgeous, and extraordinarily well crafted.
Hope this helps
