Using the Torpedo live with the POD HD would be amazing, but for a few hundred dollars more you can get an Axe FX.. Which is the exact same dilemma I'm in now.
I'd say the torpedo live would be a better choice. The quality of the cabs that torpedo lets you have is far above any other IR loader in my opinion. It also gives you the flexibility to have a cab box if you have an amp head you like, or find one you like without having to buy a cab!
