Bakpack or Prizm???

[fresh]

thank you all for the reply (against) the prizm... However, nobody answered if a bakpak would be any better? I might have access to a bakpak, so would that be much better than my prizm or more or less the same? Is it worth spending some money to get the bakpak?

I guess the question is: how much different is a bakpak compared to a prizm???

thanks again.
