If you plan to do mainly outdoor stacking I would recommend to you the SR-90P. The base unit is compatible with Arca-Swiss system, so you can mount it directly onto your tripod. Because of it's construction the SR-90P is not as stable as the QOOL Rail, but as you are not going above 10X when you stack outdoors it is stable enough for outside. For stacking at home indoor you can work without any problems also up to 20X with the SR-90P.

The QOOL Rail is more heavier and stable because of the construction where the camera plate is sliding on four wheels. Therefore the QOOL Rail is recommended for use at home while the SR-90P for outdoor. The SR-90P is stable enough to up to 20X, the QOOL Rail can be used for stacks up to 80X or even 100X how some customers do proof.
