Question for you Essence throwers...

Disc Golf Beginner here...

Got started last year and have been sticking with Discmania. My first Putter was a P1 and my first own disc an MD1 and it's still my most used disc. I've been using different Essences as my driver, for almost all tee shots and some approaches. I still don't have a "fast arm", but I get the Essence to go dead straight most of the time, sometimes drifting a bit to the right (right hand back hand) and almost no fade to the left at the end. Of course if I put it on Hyzer that shot looks different...

What would you suggest is the next (soft) step up in stability? Found a S-Line CD1 second hand that is on it's way to me. Any other suggestions? I want to slowly work my way up...

Thanks in advance!
