Field guide #6 anytime soon?

[Matthew Sebring]

Despite having received it only yesterday I've read working rope #5 numerous times now, have memorized most of it and tried my hand at a few of them - FANTASTIC work (I'm sure you've heard that many times) and highly reccomended to everyone. Now for the question I'm also sure you've heard many times - What's the ETA on book #6? Also, what is intended to be included in that volume?

Speaking of splicing, what are your thoughts on splicing Marlowbraid? Have you had any luck with the covered threestrand stuff?
