The WE mono tube with a revalve is a better choice than the WE piggy back. A good mono revalve will run you about the same money.
If the piggy’s were rebound adjustable it would be a different story. In reality piggy’s need a revalve as well.
The problem with both shocks offered from Polaris isn’t the compression side but a poor rebound stack. Rebound plays a large role in ride and handling.
The new 2019 springs are another component we will all need to keep an eye on. It was brought to my attention the material and drop in coil numbers may fatigue the spring. Keep an eye on uninstalled spring length and rate.
Here is the issue associated with the implementation of the high flow piston in 2019. The rear track shock is taking the brunt of the failures. This is just an example and the worst one to date. It is completely perforated.
