So I finally had a chance to ride my bike with long link and Öhlins TTX22 M.2 with 502 lbs/in spring which gives me 29% of SAG.
Since some riders reported problems with bottoming out the coil shock when set at around 30% SAG, first I took the bike to the city and hucked it to flat. My Fox 38 completely gave up bottoming out hard while the Öhlins TTX22 M.2 was smooth all the way. You cannot tell if and when the travel ends. I was simply blown away, just like my fork.
Next, I went for a ride on the known trail in the woods: jumps, berms, and downhill sections with big roots. UNBELIEVABLE! I forgot how compliant coil shocks can be. The rear feels much more planted, it tracks the terrain like crazy. I can only compare it to my 190mm travel analog bike with CCDB coil shock. Smooth and plush.
There is one problem however. Now my fork (Fox 38) feels like crap compared to the rear suspension. I think Smashpot should fix this and make front and rear suspension feel more alike. For reference, in my analog bike I have Marzocchi 55 RC3 Evo V2 Ti + Avalanche Cartridge. It's the definition of how the fork should perform. Hopefully, I can emulate this feeling by converting Fox 38 to coil.
