Couple of questions. . . .

[Soundtrack2life]

I have a lot of soft synths and feel that I want to expand my pallet. Not to mention if after a period of time if that changes the hardware unit will have a better resale then software. Also I use Pro Tools 9 HD3 & Logic 9 on a first gen intel Mac Pro how well does the Total Integration feature work? FWIW I don't mind committing to audio tracks as I record. So I don't need to keep the Virus tracks virtual for the entire session. I was considering the Snow model but I really think I will regret not having all the knobs and buttons. If any one could answer my questions above I would really appreciate it to help me decide if the Virus TI2 Desktop will be a good fit for me.
Thanks!
