would be what I recommend as well. Install a SSStrings Maxx kit
, and have a really trick setup.
Binary cam bows (like your Guardian) are very sensitive to cam timing. It's been my experience that other fall away rests, that have the trigger cord attached to one of the cables can affect cam timing when at full draw.
It might seem like a very small tug that those rests place on the cable, but in my testing using a draw board, I've lost up to 10% of my letoff because of a mistuned conventional drop away rest, and this slight pull on the down cable.
The Limbdriver doesn't have that problem.
Others have stated it's the most accuracy forgiving rest if properly tuned. I've gotten good results with all the drop aways accuracy wise, but the Limbdriver was the only one to give me all my letoff.
