Japanese black pine choose front and help roots was created by Ziyao12

Hey,
This year i got this japanese black pine, but i’m having a few issues with it.
First of all it came in a loam soil.
I’ve read that JBP like sandy, loamy soil but it’s not well draining, so how can i remove it and replace it with a regular bonsai/ pine soil mix?
Should i do it in one or multiple repottings and how?
Then, there are at least 2 very thick roots that i need to get rid of.
Can i just cut them all off? Or should i cut one of them like this autumn and the other one next spring?
I made kind of a shari on one of them, because
bjorn bjorholm did so on a cypress once, to weaken the root so that the tree didn’t depend on it too much
so he could cut it off later.
And then how do i get a nice nebari on this tree?
Lastly, i cant decide on the front of the tree.
I have 2 different fronts in my head.
One has nicer branch placement and trunk movement but has some flaws like the primary branch coming out of the trunk at a weird angle or the base of the trunk looking a bit squeezed will that go away or covered by bark?) .
Honestly the other side is not great, but has some cool, interesting surface roots. Do you think this side is doable?
Thanks for your advices and opinions!

First of all, I hope it is not inside. If it is then get it outside. Next, the only way to know what the roots are like is to take it out of the pot. Do not use loam, you need Akadama and pumice mix or similar. No organic material. As for front, the side that the apex leans forward will the better one, but that can change with some wiring and pruning. If you re pot do not remove all the soil, only remove about 40% depending on what happens when out of the pot, if you can save some mychorisa and put back into the pot.

I am always amazed how people buy mature trees and emedantly after getting it home start to wonder how to change it. My approach when buying mature trees is to buy the one I like and that only needs development not restyling.
Repotting should be done in late winter or early spring. In most of nortern hemisphere now it is too late.
Your tree is healthy and has proboably been in the mix it came with for quite some time. That indicates that the soil is not at all any threat to the health of the tree. Not ideal for nebari development but still no issue.
