I'm running a 160 pump with Hamilton V2.75 cam on our half ton shop truck and I love it. You can drive it like a stock truck totally clean if you want. Made 585rwhp on 340cc with small compounds.

Below 400cc the 160 b&p with V2.75 (setup correctly) has a shorter duration than a 903 bosch cam and 13mm b&p.

From a cost standpoint most guys will go with a mild 13mm because the cost isn't much more than a cam and all the other goodies installed in a 12mm pump.
