Девайсы для СОЛО восхождения, есть вопросы!!

Хотелось бы услышать, увидеть (фото) как переделали гри-ги под соло.
И есть ли смысл в покупке конкретного соло девайса или гри-гри вполне подходит.

Solo-Aid

Similar in design to the Soloist except that the Solo-Aid requires manual feeding of the rope through the device. Unlike the Soloist, the Solo-Aid will lock even when inverted, increasing its ability to catch a head first fall. The solo-Aid comes with a detailed instruction manual which must be read and understood before using the device.
NOTE: This is not a device for novice climbers. It requires a strong understanding of advanced rigging techniques.


Soloist

The one tool for solo climbing. A directional cam allows rope to feed through automatically as the climber advances, yet locks solidly in a fall, without rope damage. The Soloist is suitable for lead climbing or top roping and you can also rappel with it. The Soloist comes with a detailed instruction manual which must be read and understood before using the device.
NOTE: This is not a device for novice climbers. It requires a strong understanding of advanced rigging techniques. The Soloist must be used with a chest harness because it will not lock when inverted.


Silent Partner

Solo climbers have wished for a speed sensitive device that would automatically feed out rope while the climber advanced, but quickly lock in any kind of fall. The Silent Partner accomplishes this. It has a speed dependent mechanism that allows rope to easily move through it at typical climbing speeds, yet lock up in a fall. The Silent Partner attaches to your waist harness; no chest harness is needed. The device resembles a pulley on steroids. To use, the climber ties a clove hitch around the wheel. Inside the wheel is the centrifugal mechanism that allows the rope to smoothly feed while climbing. The increased speed of a fall causes the wheel to lock and the clove hitch stops the fall. There are neither sharp teeth nor radical rope bends, so the device is very gentle to your rope. The Silent Partner has been proven on many diverse climbs by a variety of climbers. It can be used for leading or top roping. The unit is very strong and damage resistant. It will catch a fall in any attitude, whether upright or upside down. NOTE: Like any device it must be backed up — never trust your life to a single tool. The Silent Partner comes with an extensive instruction manual. The device is totally CNC machined from aerospace alloys — no castings are used.
