As for the Darkside, it is more addictive than springers in most opinions due to accuracy and range capabilities. It is also a slippery slope which is hard to get out of, hence, "The Darkside". Plus, We have cookies on the Darkside! lolAs for the UK pressing more for PCP/HPA I think some of it may be due to the colder temps there which does not allow for effective use of CO2. Therefore, building and pressing PCP/HPA is the logical solution. Just my two cents worth.Matt
