Thanks, that makes sense to use terminal towers! Shame about that D90 L2! So far I only know of 3 in the UK, so I am hunting to find more.
I'll check out those L8DT90 towers as i've never heard of them
Also is it me or are L7 pylons a miniature version of the L6, and are L4M's a smaller version L12?
Kind regards, Felix
