Is nPath still practical?

Hi We want to use F5 LTM to load balance local DNS server. We have F5 LTM implement as one-arm topology but we need to preserve source IP for DNS traffic. = No SNAT. So I check and find that...
application delivery
dns
LTM
npath

Just remember DNS is/can be UDP and TCP which unless i've forgotten a config is two sperate Virtual Servers. One for UDP and one for TCP.

    So we just have to create 2 virtual server (  UDP 53 for DNS query/response  and TCP 53 for zone transfer)

    There is no problem to use nPath

    Am I correct?
