EWP, if you find a good one, or create a good one, nice. MOST are leggy, smooth bark, trees with pompoms of twisted needles that NEVER look convincing as bonsai. Start a scots pine, a JWP, a mugo and a JBP at the same time as your EWP . You will see how much easier the other species are to work with. In less than a decade, even the most stubborn EWP fan will compost their EWP, just because they are difficult to work with. Vance Hanna is the only exception I can think of, and he put 40 years into making his EWP presentable. Imagine how good a JWP or scots pine would look with 40 years of work.
