I just spent my first night in the Greylock 4 (29°) and I noticed one difference between its little brother the Greylock 3. The cinch chord is different on the Greylock 4. It is integreted into the suspension. I am trying to understand why it is constructed differently. The Greylock 4 doesn't seem to move freely on the suspension like the Greylock 3 does.No difference is mentioned in the product description. I am assuming this is intentional but i don't understand why there is a change between models.
Greylock 3
If you notice (on the Greylock3) the cinch chord and chord lock are independent of the suspension.The Greylock 3 under quilt comes equipped with full length, channeled shock cord suspension that allows the user to make minor adjustments to their under quilt position. For those desiring to use the traditional JRB corner under quilt suspension the Greylock also comes equipped with corner mounting tabs
Greylock 4
On the Greylock 4 the cinch chord and chord lock are integrated on the suspension line and there is an additional piece of grossgain that is threaded through the chord lock and sewn to the UQ. I do not know if this allows for a tighter installation. I always use the triangle thingies (attached to the corner mounting tabs) to keep the UQ from moving. I may not need them now. The UQ doesnt seem to move.The Greylock 4 under quilt comes equipped with full length, channeled shock cord suspension that allows the user to make minor adjustments to their under quilt position. For those desiring to use the traditional JRB corner under quilt suspension the Greylock also comes equipped with corner mounting tabs.
