Link Controller Load Balancing to ISPs (OutBound Load Balancing)

From the LC configuration Guide i can see :

1-The Link Controller system supports the following static load balancing modes:

• Drop Packet• Fallback IP• Global Availability• Ratio• Round Robin• Static Persist• Topology

2-The Link Controller system supports the following dynamic load balancing modes:

• Connection Rate• Completion Rate• Hops• Kilobytes/Second• Least Connections• Packet Rate• Round Trip Times (RTT)• Quality of Service (QOS) • VS Capacity

Question1: The above methods is mentioned under chapter called inbound load balancing , also it is configured on the Wide-IP level ( not on Pool level ) , does this mean that it cannot help for outbound load balancing ( users surfing the internet from behind the F5 , Vs=0.0.0.0/0 is configured with 2 pool members as my 2 ISP routers) ?

Question2:

Now we are very concerned with outbound load balancing ( users surfing the internet from behind the F5 , Vs=0.0.0.0/0 is configured with 2 pool members as my 2 ISP routers) ……. From LC GUI I found 2 options :

Option1: On Pool ( Ratio , observed , least connections , Fastest , predictive ) ….This options can make sense with LTM device as the pool member is a server for which LTM can get the above data about it , but with LC does it make sense with outbound load balancing , if I applied least connections for example will LC forward to ISP with the least connections ?

Option2: On Link level , there is an option called “Weighting “ , it has 2 possibilities in a drop down menu : Ratio & price ( price is dynamic Ratio which take into consideration the Link price increase per usage ) ……….. shall I use this or use option1 mentioned previously or I can use both for outbound load balancing ?
