So, Monkey v4.3 didn't fare much better than v4.1 or v4.2, although at least it went badly in a different way: the first, nearly-finished, cuff is difficult to get over my foot. Since none of my previous Monkeys have this problem, I suspect it's entirely my doing (the presence of 3,832 other finished pairs in Ravelry would seem to confirm this suspicion!).
Heather is partly silk, so it's less elastic than the mostly wool yarns I used for versions 1-3 (Ellen's Half Pint Farm merino (or merino and nylon?) sock yarn, Colinette Jitterbug, and Socks that Rock, respectively). Rather than compensate for this, I decided to use slightly smaller needles than called for in the pattern (US 1.5/2.5 mm, rather than US2/2.75 mm), because I think my Veil of Leaves socks, knit with Heather on US 2 needles, are slightly floppy. Typically, I can't decide whether to frog the cuff and start again or frog and take the third wonky Monkey attempt as a sign that I should work on something else.
Like another sock! I'm the July designer for the Sock Knitters Anonymous SockDown! Sock Knit-along (that's nearly as unwieldy as my position title in the leadership of the sub-section of the professional organization I'm involved in!), and it might not be a bad idea to get started (although it will make for boring blogging, since it's a mystery knit-along). Especially not a bad idea since the theme (either for July or just for my design, I'm not sure) is microgauge (which they're defined as more than 9 sts/inch), so it's possible that the sock will progress slowly.
(Could I have fit more parenthetical comments into that paragraph?)
