I won't even say I "know" how to install gears even after doing this one, I just applied the knowledge I have in the best possible way I could and hoped for the best.
I would still be weary to setup a rear set that would be used to drive at higher speeds for longer periods of time and that's why I chose to try a front set first.
I just did a lot of reading of various tech articles, manufacturer instructions, and watched some youtube videos by technicians.
I have a bit of experience of working with bearings from the pump repair shop I worked at for 1.5 years, just a few tricks the guys there have been using for 20+years and applied that knowledge here, but all in all it wasn't nearly as difficult or scary a process I had imagined once I was well into it and going through the motions of it.
I'd say go for it and you'll be surprised.
And yup spooled in the front on the basis of cheap, reliable, and strong.
