Again, if you’re going to dick around with clone tips, then just cancel this entire exercise and buy a Pinecil, TS80, or TS100 and call it a day. The entire reason to use JBC is to use their tips; using clone tips is stupid.
No, you can get clone tips that will give you better performance than a pinecil/ts80/etc. There is a large variety in quality.
But since there are no guarantees on quality -- even ordering from a known vendor is no guarantee that you receive the same quality as before -- why bother?
I think chasing after good clone tips is a fool's errand. The reason to use a JBC station, or clone, is to use real JBC tips.
