I like the last pic in your post from Tuesday at 11:06. That looks very interesting, nice motion and taper, and should largely be doable without a lot of wiring, or ‘clip and grow’. I think the base trunk has a lot of potential, and that 45 degree slant into a 90 degree bend is very cool.
I think you tumbled into a hell of a find for cheap, and that could end up being a very sexy shohin. Take it from me, though...there’s a reason why they call ‘em firethorns. I knocked one off the edge of my bench, and reflexively grabbed to catch it, punching two holes in the fleshy part of my thumb. I used to be into aquariums, and the punctures were reminiscent of when I got stung by a fuzzy dwarf lionfish while cleaning a reef tank.
