Load balancing the traffic other than http or ssl would surely be a nightmare with the CSS as they got very limited options for adv load bal techniques in order to implement session stickiness. Use either of these methods sticky-srcip or sticky-srcip-dstport.
You can use
keealive type tcp
keepalive port 3389
balance round-robin
advanced-bal sticky-srcip
Do not use any application type. Remember you have the threat of mega proxies if you use src ips as adv bal.
Thanks
