Aside from it being a poor candidate for a host of reasons, it is altogether a boring plant when trying to conceptualize as a bonsai.
It is a nice but overused tree for screening in the landscape. They do have their problems though even as a landscape plant. They seem to be fairly brittle and I have seen large ones (30'+) snap in high wind. The biggest problem is that they have been so overused for the past 40 or 50 years, that they have developed a host of problems with insect and disease resistance, and with genetics as well. As a landscaper, I haven't planted one in about 30 years.
