Freeps could use more copies of 
Aragorn, HttWc, or maybe somethig (
Sam, Son of Hamfast) to remove burdens and help  biding high to pull Aragorn at site 1. Burn Sam ASAP so you dont give him the 6° companion.
An Able Guide needs quite a set up to work, shadow player has to leave Twilight unused, maybe 
Gondor's Vengeance, or 
Pursuit Just Behind could help you double moving. At this point youll be needing 
Might Of Numenor to remove the exertions.(if you choke well his expencive minions will be in hand, or unluckly in discard  

)
Moria seems like a problem since you have no condition removal, 
PATHS might do the job, wich also fits the 
Greenleaf - 
Aragorns bow - 
A Ranger's Versatility strategy.
Armor is a must to deal with Uruks, maybe not too many since youll be choking, but as stated before can help against the balrog (only if you get a gondorian with his weapon).

Filibert Bolger, Wily Rascal is great against Nazgul and the Balrog, but keep in mind how often you want to use 
Sting.
The Council of Elrond seems way to expencive for a choke theme deck,  nice deck size reduction, but 2 its a lot of pool. So far never played 
Hosts of the Last Alliance, seems nice, but expencive again.
I would suggest:
+1Sam, 
Son of Hamfast+1 
Armor+2 
PATHS (3 bid+1Prancing Pony+2 
PATHS-3 Sam =3 Burdens seems right)
+2 
Might Of NumenorIf you dont get to start with a bid of 3 kill them in 
Ford of Bruinen!  

 Hopefully... 

-2 
The Council of Elrond -2 
An Able guide-1 
A Ranger's Versatility (if you started, rivers come from site 6 on, unless facing Nazgul)
-1 
Hosts of the Last Alliance.
Shadow side could exchange 
Goblin Runner for 
Morgul Gates, also better use for  
Morgul Skulker 
If you are planing to add burdens, Balrog takes away your site 5, so i would consider adding 
Must do without Hope here youll be needing to cycle before(to get) and after(get rid of) 
MDWH, so  
Gwemegil looks nice.
+2 
Gwemegil (First one Cycles the other)
-1  
Asfaloth+1 
Morgul GatesThis leaves 33-33 deck but with Cycling 

Add a 
Enquea, LOM, and if you draw him early discard and recycle with 
Morgul Skulker.
+1 
Enquea, LOM+2 
Morgul Gates+4 
Must do without Hope-4  
Goblin Runner-1 
Ulaire Nertea, Messenger of Dol Guldur-1 
Wraith World-1 
Ulaire Otsea, Lieutenant of MorgulWell, I think i went too far on the review 

 but, anyway hope its usefull.
