Ok I looked at the one that you sent me in the email,  with the player starts and stuff.  I think I figured out why you have a black line on the blue side.  i believe if you go top view,  and select the BSP box right infront of that tank,  you will see it isn't aligned on the grid,  it is so very very very slightly off.  What you do is highlight it,  then ont he corner dot,  just right click it,  it will automatically align it to the grid.

Few Suggestions,  The sheidl belt/berserk I think it a nice added touch,  but it worries me that a good sniper up in that hole will rape the field way to bad.  Plus it is to easy a flag route,  once your in there all u do is walk backwards and spam rockets down that hallway and you should be home free to a flag cap.  I wouldn't say take out the hallway,  maybe just don't have an opening at the top,  would stop the sniper from killing the entire field,  and way to easy of flag runs,  that that just my opinion though.

Also I'm not sure if you want to block the tank like Hedsteem did to go in the flag area,  In one way it don't bother me cause with jump boots it easy to take a tank out in that position,  but in another a good tanker will basically rape the map with it back there.  you get 2 good tankers on both sides,  it will become like corruption only with those people getting more points.  If you did plan on putting them in though never mind that. Also the blocks right behind the flag are more wider than the Hedsteem one, though I figure you went more actually size of how it should be than they did,  but it is hard to drive the tank through there, maybe make the ] block right in front of the flag a lil bit less wide,  but again that's just personal taste.

Other than that I like what you did.  Adding the shield belt will definitely help the map be capped easier.  Though adding the opening at the top might make it a rapetastic time for a sniper,  though with a tank could easily shoot up there,  its debatable,  would have to play it with real people to tell.  Also did you know you have A deemer in the middle locker,  not sure if u knew it was there,  don't think that will be a great idea either since you could just camp that to get redeemers,  it will basically become combat deemer hell.


Also the spawns right behind the tank,  I would say move them over to behind the block where the jump pad and weapon locker is,  as it is now,  people would just snipe spawn camp them,  least with the block in the way of some of them it would prevent some of it.

As far as the music goes,  pick a stock epic map that has the stinger sounds you like,  like the sounds after you grab a flag and such.  Necro is a good one suspense is as well.  Anyway you will have to duplicate the epic one into your own package,  then you can import any music you want,  and just change the music portion of there music to the one you imported.  it sounds complicated but it really isn't.  Void is a good guy on that since he was the one going around redoing maps to add stingers in.  But i should be able to point you int he right direction for that.  For now though pick a stock epic map that has stingers you like.  Open that map up in the editor,  go under your World Properties,  and under Map Music,  find out where its located.  I'll have to go find a link for you to show you how to duplicate stuff from epic packages to your own.  Just let me know what map you want to take there's from and I'll type back what you will have to type and stuff to get it to work.

As far as the music not being loud enough,  I have ran into the same problems,  I had to have my music as loud as i could possibly make it before I imported it in.  For some reason the loudness went away when I imported it into the editor,  why I have no clue.  If you ever play War-Subway you will see what I mean with the train announcements.

Oh well my work shift is ending man so I got to get going,  I'll get you the link on how to duplicate stuff out of stock packages and put them into your own.
