Alright honestly, I'd say this was a close battle.

Ecko I think you spent to much time on lines up'n C.S than actually battle'n F.I.

im murderin this nigga wit fucken ass roman things
stabed this nigga in da heart hit em wit a spear and a chain
- this is a good opener

he gon dissed crhyme sindicate jus so he can claim the fame
but imma beat this bitch and put em on the wall of shame
-This is where i think you went wrong, I think you spent to much time defending C.S than actually using these lines to do damage with

u wanna fucken diss me..u cant even trick me...wanna diss crhyme sindicate...
guess wut now u have beef wit me..nigga u need to get at me...
-This is another example of what I said above.

this nigga wanna clat me?now he wanna rap me?
this nigga cant do shit..u fucken pansy.
-Not a bad punch, didn't hit to hard, okay for muliti

after this battle imma leave u busted
my hardcore reign gon leave u fucken rusted
-not a bad but after this you kinda left the bar type style, which isn't bad cause the flow and multi's picked up,

Chryme sindicate gon leave u fuckin dusted..we the crew that u know u cant fuck wit
flow inteligent is jus a recent development gets his rhymes go ahead watch him fuckin embezzle it...him and his bitch e looch wont even stay true to one crew so fuck u
next thing u know he'll be crawling back to the same crew... wow... what a tough dude...u act hard but u really a pussy...fuck wit me and ur gon wish u never fucken pushed me.. eckos gon hit hard wit shit thats to intricate... u know he's mobbing wit the fucken crhyme sindicate...bitch u should change ur name n ur flow aint intelligent... u know u cant fuck wit the devils advocate...u need to change ur name to Kan't flow...crhyme.sindicate is rb's fucken best maestro..we tight yo
we murder fagots like yo... who talk shit but just cant get through... the ones that suck cock to get to the top... the ones that stop drop who try to act like 2 pac... ecko made u his bitch i aint even 2 pac

----------Flow Inteligent-------------

im sorry for hurtin ya feelings and callin u a skill-less fucker//
cs dont stand for crhyme sindicate it stands for cock sucker//
-this is an allright opener, I'd give openers to Ecko

my segments-savage i shred and ravage this fuckin faggot//
so my spit keep you in more heat than a pregnant rabbit//
This is a excellent Multi, finished with a solid punch

i cant "stretch" the truth...we aint in no "gumby world"//
ill drop my nuts on ecko's head like i was a clumbsy squirrel//
-This made me laugh, as well as a good punch

i fix fakes..trick apes..connect my punches and leave u fist raped//
plus ill have you all "strung out" like a fucking "garth brooks mix tape"//
-Wasn't really feel'n this

ya skills aint past average get stretched in a plaid casket//
you might as well drop rap like text was a bad habit//
-The fist line i wasn't feel'n but the one after was realy good.

my rage spittin is page splittin..yankin grills like im a crazed dentist//
and i guarantee you'll receive the total vote equal to our age difference//
blaze hittin with punches that will phaze quickness//
and rape u till your sic of sex like permisquis AIDS victims//
-Again, good use of multi's creates good flow, and the punches weren't bad

i know i got you mad and i only came half assed//
punches break ya leg so now ill write a rhyme on ya cast//
scream to say to it my team will blaze it//
crhyme sindicate fuck wit me and get they fingers braided//
-This was funny, but not realy a hard hitting punch.

All in all, I'd say this was a fairly close battle, I'm given it to F.I cause of the punches hitting harder and better use of multi's. I suggest ya battle again, I think it would be closer.
