It's been a long time since I used either but I did build my first two (back in 2004) using the Courtnall book and, if I recall, the angle worked out well.
I also built my second two following, more or less, JB's methods. If I recall, the neck angle on the first ended up OK but string height was on the low side for what I like on a classical-probably great for a flamenco. For the second I shimmed the neck end on the solera by 1mm (flatter/less angle) and ended up pretty much perfect.
Again, this is the best I can remember of the two (I haven't used either method since 2007-8). Also, this is purely anecdotal-those were my first four guitars and my skills weren't what they are now. I'll add, too, that I used my own design for all of those. Even though my dimensions were very similar to JB's they weren't exactly the same so that could possibly account for the string height ending up a touch on the low side for the first...though I kind of doubt it: I used the same scale length and the lengths of our bodies only differed by a couple of millimeters.
I think you'll be fine using either but I'd definitely pick one method and use it all the way through. Don't mix and match pieces from each method on your first.
Edit:
Also, I don't have the book in front of me now (it's at my shop) but, with the 25' radius dished out of the ramp, I don't think you're anything like 2mm over the main plane of the solera at the bridge position...I think you're pretty close to AT the plane of the solera (close to 0mm).
