This puzzle contains one or two steps that are mildly similar to something I did in this puzzle: Ctc tribute. You may like to check that out too if you like this one, or try it first if you get stuck on this one (or vice versa, no idea which one is more difficult).
(Edit: I just realised they are much less similar than I first thought, due to a step being slightly easier than I had tried to make it, and me not realising the easier version of the step was possible.)
You might also like to check out my first between lines sudoku Cycle, which could use a few more solves.
Last but not least, my recent puzzle Questionable Chaos, which I'm quite proud of, could use a few more solves as well.

Have fun!

Rules of this sudoku:
Normal Sudoku rules apply.
Along thermometers digits must increase from the bulb end.
The value of digits on between lines must be between the values of the digits in the circles on the ends.

No bifurcation is neccesary!

I'm not entirely sure about the difficulty of this one, probably 4 or 5 stars.
