Replication better Approach

Hi All,

I want better approach for example:-

A- Publisher in Kol

C- Subscriber in Kol (want to used reading purpose only)

D- Subscriber in US (want to use reading purpose as well HA)

*Insertion/Updation/Deletion only one end on A publisher

for same scenarion i am thinking doing peer to peer or transaction replication with queue updating .

if I am using transaction replication with queue updating with Pull Subscription then add B for distriutor.I think this is better because if transaction not go in Subscriber then overhead to the distributor .....

I am using SQL 2008 R2 Enterprise.

Please let me know which one is beteer approach in terms of performance...

I have another option :-

A- Publisher in Kol

B-Distribution in Kol

C- Subscriber in Kol

D- Subscriber in US

but this doesnt provide HA but i am thinking adding HA as well and remove mirrioring.I have no issue for down time for 10 min (change application path like that)

Thanks..
