Cheers Mike - have had a lot of comments saying that folk appreciate the depth & how I leave nothing out - have had others say I go on too much & the review is too long! You can't please all of the people, etc, etc! My next one is going to be my new PF500 head & I've decided to do it in bookmarked sections so folk can either watch the whole thing or jump straight to the bit that interests them - seems like a good compromise! Thanks again, Darren
