I got out to the bonsai shelter today and took some pictures. Unfortunatly I am using the old fashioned 35 mm so nothing to share. Howerever good new. Now that it has finally dropped it's leaves (yep I cleaned them off the soil) I can see something I missed last spring when I last saw it leafless.
When veiwed from a few degrees to the right of my planned front the seperation between the two trunk is more obvious. If I do need to increase the "V" more the wedge sounds like a good plan. Thanks for the idea, I hadn't thought of that.

But here is the surprise. The taper of the lower trunk is MUCH better. I let several branches remain on the lower few inches of the trunk and they really worked some magic. I also have the good fortune to see the perfect new leader grew last season exactly where I wanted it!!
ripsgreentree- I have NO idea about the roots. I hope that the rocky/gravel native soil has given me some nice feeders but I wont get my hopes up. It is going into a large shallow(ish) nursery pot. I have no intention of putting any of my potensia into pots yet. I'll admit it my first year I had three laughable maples in bonsai pots. LOL Yes that was stupid. I now have about 10 nice japanese pots on a shelf in my house as I know I won't have a use for them for many years.
Thanks for the help all.
