Distance and bullets power, sure, thanks:) Looks like i still stuck with my gun...
About tests - i did start work on ConceptA because Tomcat now has high coupling (cohesion?), so test it is difficult task:) But any way thanks for advice:)
I agree, that big things is better, but i think, that APS gap between Tomcat and Diamond and DrussGT just in "tiny tweak", which require hours of tests. But tests is problem for me with my low-end first generation mobile i3 core:)
