Thanks again Guys.
Mictoon, the "swoosh" is on the right track, (esp, 24 & 25) however I think it has to be bigger if we are going to emphasise it - perhaps some smaller and neater eg 24/25 and one or two with a rough, "brush style" red swoosh - it definately has to be a tick, though going from Left to Right.
26 is the closest to this - maybe with a deeper blue green and the tick running behind the L and up over the P, so it becomes a dominant feature. Would need some sort of lightening behind it so that the letters would be distinguishable if printed in grey scale.
The Green shade we could use is a very deep sea green / blue.
