I got to shoot the Katera and the Katera XL during spring break, along with a bunch of other bows, and I prefered the XL over the regular Katera. You're guess is right on, I thought the XL was much more stable post shot and while holding steady at full draw as well, just more balanced overall to me.
I'm assuming the draw cycle is pretty much the same as well?
