Creature Handler Archive

I am going to respec back to CH. CH was my first profession and I loved it. But with the CU here, what are now considered good pets. I used to use two GSP as my tanks. I still have them on my data pad. But I was wondering if the are still "good" pets to use or Do I need to go looking for some others? I also have a Grual and Toxic Merek Battle Lord. Just looking for some good pet combos to have out.
