Thanks Chaps,
I have now talked myself round in circles. However, I think for my purposes I will give the Delta a go. The Spade is a bit pricey and the Rocna and Manson suggest they may require alterations to the stemhead and/or bow roller.
Many thanks for your comments and if you see a Bav30 ‘going with the flow’ you will know I made the wrong choice.
Cheers
