The 62+ part is key with SAM. I hit 62 yesterday and was alarmed by how much more kenki we generate with Kenki Mastery II. Thankfully we get Shinten at 62 also but I didn't think to test out the new stuff before jumping into a dungeon...it was like I put my shoes on the wrong feet. It was disorienting at first to go from a slow trickle of kenki to it spilling out and needing to get rid of it lol. Good stuff, though. If you loved SAM before 62 you'll love it more after that. The playstyle kicks up another notch.
