That sounds like a great approach, Potawatomi13. In post #1 I mentioned the raison d'être of this tree is to learn and better understand the refinement process of JBP. I've got 50 one year seedlings, 5 two year seedlings, 5 four year saplings and 1 six year old in development that I plan to learn the grow out process on. For this tree, despite its flaws I'd like to practice refinement and see how it affects the tree so I can be better prepared when the seedlings reach desired trunk thickness and taper over the next ten years. I'm not necessarily saying I'd like an ugly tree, but I want to learn this aspect of bonsai.
Just yesterday, while pulling old needles I learned a valuable lesson. On several pairs of old needles, I pulled and took a new needle bud with the pair. I'm guessing in the future I should leave these old needles until the needle bud develops or pull closer to the base of the needles like a surgeon, lol. C'est la vie! Getting my hands dirty after reading is providing new realities to what bonsai is vs what I thought it was over the years essentially just growing pre-bonsai.
I appreciate your thoughts and insight. An approach I might consider if I had different goals with this tree.
