Hey,
Fubar and I will be pushing out a new version of barnblitz this month, and we'd like any constructive feedback that people have.
We're aiming to be a little more experimental with this version than in the past, here's the current proposed changelog

It's worth noting that, according to comp.tf, barnblitz pro6 went unplayed in any UGC season, and there were some pretty large changes made from pro4 to pro6 - here is an incomplete changelog between those 2 versions http://pastebin.com/2cLuuZB7
As such, if UGC was the last time you played the map, there's a fair chance that your complaints have been addressed already (ie: difficulty pushing last).
But yeah, any feedback/suggestions would be appreciated
