hi! i just started an apprenticeship after 2 years home tattin. i was using t-tech cartridges for a long while and had lots of trouble with ink flow, mostly with the 1003 and 1005. my mentor had me try his kwadron needles, same size and they were amazing, great flow, i wanna switch over all to this brand now but yikes its moneys to switch over. has anyone found a brand they find to be solid. i thought t-tech was tops, but maybe just the smaller grouping, just so hard to work with. thanks!
