Ben, I have to disagree with you on this. I have worked with a number of PICK installations that always use type 18. I can frequently find a better hash type for their files with a bit of effort. (MHC installations are *easy* performance improvement sites, for example.)
The file types are there to be used, not ignored.
As to modulos (modulii?)--odd numbers ending in other than five are not necessarily prime. Prime numbers tend to work best in an algorithm based on a modulus divide. Choose the next largest prime number.
If thinking about file parameters is too much effort, I highly recommend FAST by Fitzgerald & Long.

You'll almost never have bad (clumpy) hashing if you use type 18 (which is the default type in PICK and REALITY flavor) and if you use a modulo whose last digit is 1, 3, 7, or 9 (that is, any odd number not ending in 5.)
