You can style Alberta spruce so that they look amazing. Then they die.
You will learn something. Not to use DAS.
All of us only have so much time on this Earth. Use it wisely. Others before you have tried DAS, and learned it only brings heartbreak. Especially if you are new to bonsai, use the tried and true species to "Learn from". You will enjoy the journey a LOT more.
Eastern White pine always has long needles, and long internodes. They never get that "full" look. They don't develop nice bark quickly. Again, pass.
I've been doing this over 40 years. In all that time, I've never seen any good DAS or EWP. EWP will live, but the final results aren't worth the effort.
I'm not here to insult you or anything like that. I'm trying to get you started on the road to success. You'll have more fun with the traditional bonsai species, at least to start. Once you get some success under your belt, then you can try more difficult subjects.
