i may be wrong here kelly- but it seems the way these siyahs are built- you need the larger loop to slige down either side of it, with just a bowyers knot the string would slip of one side or the other.
and yes grey- there are a bunch of different models- on grozers site there seem to be dozens of them- it was primarily( and i might very well stand to be corrected on this one) the huns who built the bows with different lenth siyahs, for the ease of shooting astride- that obviously doesnt mean that you cant shoot with other bows astride- just the history- but in all honesty i honestly cant see what difference a couple a inches would make on already crazy short bows anyway!!??
say how do you like your Grozer
mine is really superfast, and really accurate- consistant.
just hardly use it 'cos i didnt build it i geuss- just stubborn- an like to shoot my own.
the length of the eyes is also important- so that at brace height, where the string leaves contact with the siyah, is where you want the loop to be ending- too long and i would worry about it slipping off the back of the nock- too short and the string will still torque to one side or the other.
i will get some pics and measurements in the morning- and if the bows dimensions are close, i can build you a string- and lets see how it works- what is the poundage on the bow
