ok first my mag.level 7/ retro valve/no level 10, no ULT...i will be getting the Ninja SHP Tank shortly, if i leave the marker alone, as is, will my reactivity be ok???? can i get away without the level 10 and still be ok???

ok second question with my friends mag level7/classic valve/ ANS Bolt...he was asking if he got the Ninja SHP Tank would he get reactivity with his basics???? did i say this wrong with the level7 and ANS bolt???? he was wondering what he would have to do or stay where he is at to get reactivity...

i know that if we both install level 10 ball breaks would be gone....thank you
