nice guide indeed. pretty appealing for the standard person who's just starting out, but i really think that equipment is more important than anything for bowzons, so esp starting the new ladder, it would be better off starting a different mfer (sorc comes to mind) to get you started on at least some decent gear. Last season, i started with nothing with a bowzon right around 2 months before ladder reset, and after like 2 weeks, i had more than the gear suggested, but that was only because things like 20lifer scs and 7mfscs and socketed armors/weaps could trade for hrs (and then for whatever gear you would need) sooooo easily.
That being said, I have to say bowzons are still not as expensive as MANY of the other builds out there, and are really wicked fun

Another question, on rune words, what do you think about a Brand gmb bow? Sure, its prolly out of the question if you talk about non-duped hrs and stuff, but the mods on it are really crazy: knockback, prevent monster heal, explosive arrows, ignore monster defense, 20% deadly strike, and a max of *shock* 670% ed (vs. demons). Leech is easily fixed on your rings, and although it doesn't have ias, you can rely on your other items and/or merc faith (which is my setup) to still reach an impressive 9/2 strafe. Even though it is EXPENSIVE AS HELL (mine cost me 10 hrs, because i made it myself twice to get more ed), I do think it's worth mentioning at least for boss-killing.
