LB members within a redirect iRule

Have a working iRule to redirect a specific source IP to a specific pool member. Now want to add load balancing between 3 pool members within that pool via the iRule.

I know a redirect between many pools would allow for the LB method of the pool to handle this, but we want to use one pool, since we will have many redirects.

Current iRule (12.1.1 HF1 code)

when CLIENT_ACCEPTED {
set client [IP::client_addr]
    if {$client equals "1.1.1.1" } {
    pool my-pool member 10.10.10.10 1025
    }
    elseif {$client equals "2.2.2.2" } {
    pool my-pool member 10.10.10.10 2025
    }
    else {
    pool my-pool member 10.10.10.10 25
    }
}
