Super nice still trying to transition to these for lining. I switched lining ink at the same time because I was out so not sure whats giving me the troubles. In the past I cant seem to get on with any other linining ink but silverback 11. Whats needles and groupings are you using. So far I seem to line pretty well using t techs but not so much regular liners and tubes not sure how that would affect me. Got the newer kubin with the spring armature bar. What kubins are you using?
