Reply to to wait or not to wait? help plz

hi all i have the new version of traktor loaded and my black vci version 1.2
i was wondering the folllowing,

if there is a lot of bugs regarding the new traktor and tsi file should i just load the 1.3 and wait for the new tsi?

will i need to buy a new overlay, as i just got the one in the shop becuase i thought there wasnt any bugs, can i put this overlay on?

is there more benefits using the new tsi in 1.3 then using my stock vci as is...

Thanks guys i just need some help as i have everything ready to mod thats all
