Hi MusicMan!
I'm currently working on a whole high-quality waypoint pack, focusing on custom maps. I'm in the process of checking and debugging them for optimal performance. This is quite a pain in the *ss and takes a lot of time.
I have waypointed roughly 100 maps myself, and I'll finish checking my WPs for cs-maps in the next days, maybe tomorrow already. The de-maps will follow...
Moreover, I have compiled a little "personal map archive" that contains good custom maps together with hq waypoints, either made by me or by others. As soon as I'm done checking and bugfixing, I'm going to post them along with my own waypoints.
If you are interested in a little quality sample, you can take a look into Austin's thread "Need PB 2.5 waypoint for de_karachi". I posted a WP for de_karachi01 there. If you don't have this map yet, d/l it! You won't regret it...

The URL is also in the thread. And if you like what you see, just stick around here during the next days and you'll get much more.
If you're absolutely desperate about one or two particular maps, just let me know which ones they are, and I'll make some WPs. Once in a while, it's a nice change to start a WP from scratch instead of fixing & testing.
Good waypoints for the default maps are already in PMB's PODBot release. I've taken a look at them and can assure you that they don't leave much to wish for... or did you notice stupid bot behaviour there? I dunno, haven't played the default maps with bots for a long time...
