Better off using large older Infinity or small newer Pioneer?

[cinemaphile]

Hey all,

Just about done finishing my basement HT, wired for sound and everything. The only bad part is I pretty much don't have the money left right now for any real upgrading. So I'm trying to decide which speakers to use:

I have two Infinity tower speakers and an Infinity center channel that are about 15 years old

OR

I have some Pioneer speakers that are only about 4 years old, but they are the tiny style that came in a HT-in-a-box with a receiver.

I'll obviously be using the Pioneer rear surround speakers with either setup, but as far as the front L, R, and center ones, which am I better off using for the time being until I can upgrade?
