Hi AJ Barlas,
same setup - Öhlins M.2 Coil, Assegai DD Maxxgrip and Proguard "mini" 😜
I used to run the Syncros fender(a little bit to small, also don't cover the fork sealings) on my Fox 36, and also the normal Mudgurad(nice but I don't like zip's) for many years.
I can confirm 1:1 your review. I like the Proguard and does everything better that the other two. In the wet everything is fine, a lot of space for little stones and little fir cones. The only thing - the seals still get some dust, may they should increase the "sides nose" a little bit 😉
It gets my recommendation too.
