Zu,
I too was disappointed at the lack of attention my first two mods received (BEAR and Open All the Gates, which at last check were both well under 400 unique downloads even though they've been available since September); and at first it looked like WEPON was going to head the same way. But then WEPON managed to reach fifth place on TESNexus' "hot 5 mods" list and its popularity exploded. In retrospect, I think publicizing its existence here, on TESNexus, on Planet Elder Scrolls, on UESP, and on TESAlliance, as well as putting together a bunch of cool screenshots for it, all on the first day of launch, were what made the difference. (My Marketing experience at work!)
I complained a number of times on these forums about the lack of attention for these three mods, to the point that my posts devolved into whining. But then someone - I do not remember who - pointed out that the best mods frequently are not the most popular ones. For example, the Top 25 Mods list on TESNexus currently is dominated by entries such as "Hentai Lovely House", "Claudia's Little Secret" and "sixy Oblivion Overhaul". If people like that sort of thing, okay, but they're not what I would call high quality adds to Oblivion

Meanwhile, some of the best mods I use, like Wizard's Spell Book, garner almost no attention.
All I can do, then, is try to offer a little encouragement and hope that it doesn't sound as shallow as it did when I received it. Your Overhaul is an awesome mod which, especially considering how much work it represents, just is not getting the attention it deserves. Additionally, I would recommend redoubling your efforts to publicize your mod - more people need to know about it! A good start would be to put a link to it in your signature, or possibly even setting up a website devoted to it...
Regarding not answering your questions: I apologize, as this oversight was not intentional. I was bombarded with messages when WEPON first came out, and despite my best efforts was not able to respond to everyone. I do not recall your question on the Durable weapons. Were you wanting to use WEPON's Durable weapon records in your Overhaul? Or was the question regarding how the player is allowed to obtain those weapons?
EDIT: I fully agree with what migck says above as well.
