New Dovetail Guides, Which Angles?.

Despite numerous requests I've always stuck to making my guides at approximately 1:6 (10 degrees). I'm investigating various angles with a view to producing a range of guides.
The traditional 1:8 angle is the one I get asked for most at shows, so I'll definitely be making that one. My initial thoughts were to produce a 1:4 as well although when I saw the difference 4 degrees makes I made a 1:5 sample too. As you can see there is a clear difference between them. Most of my guides have been going to the US in the last year and I know the steeper angles are more popular than here in the UK.
I don't think I'll do a 1:7 even though that was Alan Peters favourite angle.
I would be interested to hear from people as to their favourite angle.

In making these mock ups I had to work free hand without the aid of magnets, I haven't done that for a while! Now I know they're not perfect but they did go together straight from the saw and each was done in 5 minutes. I'm glad I can still saw straight!
