they probably play similar because they both have the heavy 5/16/14 steel joint. making it forward balanced. Idk about Joss and their butt diameters but I do prefer smaller butts. As I only grip with my index and thumb for the most partSchon all the way between those two. Buy an older second hand one. I dont recommend buying anything predator brand.
Joss will feel play almost the same as a schon...if u get a regular 12.75 shaft or so. Joss's 13.25 is a fucking tree trunk..(makes a great break shaft with a sumo extra hard water buffalo leather tip or a sonic phenolic tip from mezz btw). If the shafts are same. Schon and joss play almost identical. Honestly I kinda like the joss better. Schon has better fit and finish.....I don't have my Joss anymore...but it played just fine. Seems like I always used a diveney lakewood shaft with it. Then I started using it as a breaker with the stock joss 13.23 shaft and a super hard tip
