If you call 9 lbs heavy, thats what mine ways in at...Now, you can strap a 120 on for size if you want unlimited vertical...Russman, told me he seen one with a G23, now thats BAD!!! As for the Ultimate vs. the Skybolt, some like one better than the other, to me its just a matter of opinion...I like the Skybolt for its curvy lines, theres not a straight piece of wood on her...Maybe I likes my planes like I likes my women, CURVY...
