Nick, I set the length of the clickers on my different bows by marking an arrow, then having my wife watch as I draw it back, adjusting 'till I get them all the same. (Note...I find that I draw shorter with a lower wrist grip than with a higher wrist grip, so they all aren't exactally the same).
I use the D loop material for my clickers as well. I melt a mushroom on the end that goes through the clicker, then glue it with something like Shoe Goo. On the end that goes through the string, again I melt a mushroom, then just put it straight through the middle of the bow string strands, then serve above it with dental floss.
I leave the bottom side unserved so I can pull the cord out whenever I need to add twists to my string. (This will cause you to have to re-do how the cord enters the bowstring.
Also, I silence the spring steel portion with moleskin....gets them pretts quiet, however some are noisier than others.
Hope this isn't clear as mud! Let me know if you have any more Q's.
