IRFP240 vs IRFP250 Ampeg SVT

[diydidi]

Been working on some SVT 4 pro's lately. Today I had to order some IRFP240's as my stock has been depleted.
I found the following in my search on RS components (big in South Africa). The IRFP250's are almost half the price of the Irfp240's.
Now my question is; can I use these in the output stage along with the p-channel IRFP9240's?

Looking at the datasheets there are some winners & some losers.

In a Class AB amp, I don't see an issue.
