Definitly not worth it.  Just save your money.

Well, thats my opion.  Some people love it, some hate it, i'm one that hates it. Lemme list some of the good and bad, and you can see if you like and are willing to take some of it.

1.Its pretty heavy (and if you lift weights and are strong, imagine all that damage you could do with a light marker!)  I just had to slap that excuse.

2.It shoots straight.  This is a good and bad thing.  In woodsball, it helps a lot because you usually can arch your gun to much.  In speeball, when you kind of need to have that arch for a ball to sink into a bunker, this thing will have you pretty mad.

3.Kind of hard to clean.  I know everybody thinks people are immature if you cant spend 15 minutes cleaning something out, but say that when you have a ball break in the middle of a game.

4.To get a good clean, you have to unso some screws and take out the barrel.

5.To take the gun apart, you have to completly take out the flatline except the adaptor.

6.Loud

Well, theres a bunch more, but thats all I can think of.  See if you can get somebody to lend it to you for a game or let you test fire it and see if you like it.

The flatline problem stated above about balls curving is a by-product of tilting your gun.  If your gun is straight upright, the balls will have a perfect backspin, and will fly straight.  If you tilt your gun to the left, the balls will have an up-left diagonal spin, and will curve, just like a curveball in baseball.  If used properly, this tendency to curve when tilted can be a nice tactical advantage.

^^^This is what I've heard from other players who know what they're talking about, but for my personal opinion you're gonna have to wait untill tuesday when my flatline will arrive and I can test it for you.

wow road runner you're pretty dumb.

The Flatline is awesome for the best range but for sniping its not the best choice. Most times sniping is bad in paintball anyway.

i have a flatline on my A5, and im very happy with it, although as notorious bob said, it is hard to clean, cant be cleaned with a battle swab. i only use it for woodsball though, because it allows me to shoot at a low trajectory to avoid hitting low branches and brush, its not as accurate as ur smart parts though, but you will appreciate the range it gives you that no one else has. So yes, i think it is worth the money, but thats just my op.

For "Sniping" (and I hate that term) you definately want accuracy as the other gentleman mentioned.  In Paintball, you will not be able to take out targets at a range that will allow you to be safe from return fire unless you shoot with a flatline...and from what I've seen Flatlines lack the required accuracy for placing your first ball on target.

You want to get something that is accurate over range here.  (To date I've seen only one marker that has a Flatline's range but maintains the accuracy of better barrels...)  Also, paint to barrel match will be critical as well as this has a great affect on accuracy.

So what you will do with this set up is get in close so that you know you're first shot is going to be on target.  Then wait for the right time to pull the trigger.  Take one-two shots and wait to see what happens.  The more you shoot the easier you will be found. If you tke your target out and there is no one around, move to your next spot.

Don't think that being a "sniper" means you set up somewhere and wait...if you want to do that join the boy scouts and go camping for real.  "Snipers" in paintball are more like marksmen...they use stealth to get in comfortable range of their target and then take it out.  Usually, these guys are also scouts and, unless you're playing a scenario game, don't really have a role in walk-on rec games and do not exist in Speedball. 

i have a flatline on my 98c and for some reason, mine is reeeeal finicky.  i love playing woodsball but living in Phoenix, Arizona, there's not too much woods to play around.  so rec-ball is pretty much all there is at the parks around here.  also, to be truthful, i'm getting kinda tired of my flatline in rec-ball.  it's a damn good barrel for woodsball, but for when you're in close range, it's pretty frustrating.

if you're a woodsball ONLY player, get it, if you're more of a rec ball player, i suppose you could give it a try, but you'll prolly want the arc that non-flatline barrels have.

Don't waste $100 on the flatline unless you can get a lot of your money back out of your lapco. as far as it being a hassle: yes, it can be a hassle IF you don't take 5 minutes to sight it in when you install it. But I'll tell you I am very pleased with the performance of my flatline. Good luck on your decision.

Can you clarify this?  What difference would a lighter marker make over a heavier one if you lift weights?  I happen to lift on a regular basis and this didn't make sense to me at all...

A) No such thing as "sniping" in paintball

B) Don't waste your money
