Honestly I would build stock but I don't want to post anything second rate, and I don't want to build yet more popups and rammers (stuff that are hard not to be second rate at comparatively) and I end up not building stock at all.
Duder, no one wants from You to build top level bots always. Although, I didn't get the impression that You are a bad stock builder... Also, for an example, not all the DSL builders are top level too, but they still build, so...
You can always make other bot types than popups and rammers. And the popups are not a "second rate bots" IMO.
