Update: I gave up. I decided not to cut it for now. Instead, I gave my Ozone Tour to my girlfriend.
I removed the foam pallet (yes, intact, I've made my own Prince L4 pallet
), improvised a butt cap, added some guard tape around the head (cheap prince paint is cracking all over) and she's good to go. If I ever want it back, all I have to do is put the pallets on. Weight now is close to 300g, a bit head heavy, but also a bit shorter than 27". Seems good for her, lets see how she'll like it.
As for the Chang, I'll leave him safe this time..
