permaculture

In selecting the trees I'll be planting in a few months, I've been been 
favoring honey
locust over black locust.  I thought that they were equal in their nitrogen 
fixing
capacity and while I have yet to read something suggesting any toxicity with 
honey
locust, I have read some positive and negative stuff about black locust.  

Now that I have learned that honey locust does not enrich the surrounding 
soil as much as
black locust, I'm thinking I need to re-evaluate this decision.  

I know that the bark and wood of black locust is toxic, but I suppose that 
that would
almost never be a problem with grazing animals.  I would guess that even 
goats would not
care for the taste.  In fact, maybe I won't have to cage a black locust 
seedling? 
Anybody know about toxicity issues in the leaves and the pods?
