i just got my new onza trials uni and i am loving it. this is my second uni, my first being a 24" muni. it took a couple hours to get a hang of it as i had previously done all my trials on my muni. the biggest hurdle is the difference in seats. my muni has a miyata airseat and the new onza has a KH. despite the fact that the miyata is brutal on the fingers, I have managed to get my hops up to about 25". on my new ultra-light trials uni i did not try anything higher than 20" but rarely missed a hop. i hope to be nearing 28" by mid january. the onza feels so much more responsive during trials. doing seat out hops on my muni felt as if i was lifting the seat, which was attached to a lead weight by a rusted chain. the onza feels as if i am lifting a single object vertically collectively. its a nice feeling :-). the frame is really stiff, which as i implied above, greatly adds to the hopping aspect.
i will now compare it to the KH20/summit
my bro and “almost” everyone in Hell on Wheel has a kh20 or summit (not frank) so i have had plenty of chances to ride them. in my personal opinion, i prefer the onza. this may be because the onza is “mine” and that implies a certain increased level of affection, but it just feels more solid, and i like that in a trials uni. i also prefer the yuni/nimbus2 style crown over the kh. this is most likely because my muni has a yuni frame and i have therefore slowly become accostumed to it. another advantage i will point out is that the kh comes with wellgos 
and the onza comes with bulletproof style pedals (not great but much better than wellgos). these differ from the bulletproofs in that they have more pins and the pins are a good 1 or 2mm longer (no i am not joking). they are massive and i will surely “feel” their grip later in riding :-). i also like that the cranks angle away from the frame to prevent your ankles from being nipped by the protruding cylinder out of where the crank attaches to the hub (sorry but i cannot remember the actual terminology of what i am delineating). so all in all, i prefer the onza. it is mine and i shall stand by it. but i guess the comparing is futile until i put it throught the same torment as has been put on the kh20s…
and perhaps i will update everyone on the progression of my testing of this uni in the future…
