theres a company called pc coils, owned by a beligian guy, his coils are pretty decent he offers both mtl and dtl coils handmade.
Another go to for me is any straight wire builds though ive shouted at my device a few times when springy wire has got me hot and flustered and it just wont go my way.
I always keep a device with prebuilt coils on hand for when i really butcher things up.
Ironically the best mtl coil i ever made was using some clapton wire meant for subohm vaping, but hey it worked, if i remember correctly they were UD wire shots.
