Mike & Jarry,
Nice variations, I'm not sure about the apex on Mikes though. Still worried about that pot in both options.
Johns virt in post #8 still gets my vote.
Matt as an idea.
Is it possible to add a poll AFTER the thread is closed ? Say put it on for a week, and we can vote on the various virtuals. We can then look back on each tree and see which one was the most popular.
(FWIW)
Cheers,
Ian
