I like the colour; the whole thing has the look of an Open UP, which can't be a bad thing.
I've spent about 2 years considering what I wanted from a gravel bike (read 'non-technical bridleway distance covering bike'). What I did know for sure is 35mm CX tyres are rubbish for anything more than muddy fields.
18 months ago I bought a second hand Singular Gryphon as a bit of a technology demonstrator, and learnt a lot from riding it for a year. The main thing it taught me is (as closetleftie coined upthread) I like a low roadie front end, and like to be able to use the hoods, which flared dirt drops don't really allow.
Ultimately I realised what I wanted was my audax bike position with 2.2 tyres so I could just let it go on offroad descents. So a one-size-smaller-than-I-would-normally-ride 29er F&F was sourced and here's where I am at the moment; similar to your yellow bike Mike, but steel and without having to build myself new sized wheels / buy more tyres etc as I have loads of 29er disc wheels. 25lbs as it is in the picture.
I'm enjoying it a lot at the moment. It has certainly rekindled my interest in Veloviewer explorer tile chasing, as I'm as happy on the road as off it. It might yet make an appearance at Iddu's Salisbury Plain 200 in August.
