Yeah as much as I sigh about the backdoor trading of Bros, some of which we never even got the chance for, there isn't really anything we can do about it since it's all via PM and underground.
Unfortunately it also pretty much means that I'll never get any of my dream caps because there aren't that many light blue/blue sparkle ones, and they're all the kind that are inaccessible unless you have a sick collection already or absurd amounts of money. I don't expect to ever be able to put any V2 on a board. My one I have is Topre, and I'm not getting any Topre boards. I don't expect to ever get a v1 Reaper. My luck with raffles is nil. *sigh* I'm still aching for this sale and everything in it, but... I just don't expect anything to happen. :/ It'd take a miracle and I'm not due for any of those. My 'miracle' was that my tire blowing out Saturday didn't cause an accident and just wiped out all my spare funds.
Agh. Too much stress.
Bro Caps is one of the best custom novelty cap producers out there, and I will give you some tips when it comes to getting what you are after.
Don't complain about never getting a or b. Try to be positive instead and just keep it visible what you are interested in. Have some info in your signature about which cap(s) that are your favorites and how much you want them.
If you have something to offer up in a trade, let it be known.
Talk to people wherever you can (join the IRC channel if you're really social), and get to know people on a personal level.
In the end you'll more than likely be able to get the caps that you are looking for without having to deal with PM purchases and over priced brocaps in the classifieds.
It will usually take time, but I promise you that if you really want something, the time will be well worth it.
