pod or pod pro - which is worth the money more?

[shapshankly]

ok, so money is not a problem here, and the question is quite simple:

is the pod pro so much better than the bog standard pod? *

the big line 6 pedal board will be used with either, so there is no real difference made by that.

at present i can only see that the pro is rack mountable and has better ADA converters, so are the tones really that much better?

i'm sorry if this is a regular topic in*the forum, i just need as much info as possible.

any help is much appreciated.

thanks

ian
