I ran the single-level XMITTERs on the FJC (12" bar center, 4" bars on either side for edge-of-road lighting). The two 8" double-row lights in the grille, plus 2"x2" LED packs as fogs, work very well on the new truck, even on totally unlit dirt roads up in the mountains.
Thanks re the Acholi, though living in Acholiland for more than a year has certainly helped. As has having many Acholi friends and a great tutor (3 days a week of intense language instruction when I first arrived for several months). And, of course, it helps that my girlfriend also speaks Acholi... helps keep both vocabulary and accent in check. I can probably get around Gulu and Oyam for a few weeks at a time without resorting to speaking English, but I usually speak English with coworkers and others to make sure we're "on the same page" if it's something important. Acholi interpretation can be a bit too metaphorical at times, if you know what I mean...
Now, though, I'm concentrating on Arabic again, as my next bit of work will likely demand a high degree of proficiency...
