Most conifers aren’t great – the resin either makes the hole/groove too sticky or it glazes the drill so you can’t produce quality dust. That said, my western red cedar (Thuja plicata) set was fantastic. Best woods I’ve found (drill/hearth board) are hazel/ivy. Hornbeam/willow. Willow/willow. Hazel/lime, but the real challenge is to go into the woods and get a fire going by bow drill without any prior prep – really tests your skills.
Primarily down to material selection and perseverance as people have said. Sycamore is a good option in the uk as it works very well and is very common. Make sure you’re using a comfortably long bow as well, have the string sternum to finger tip in length.
