I find line twist always occurs to some degree, but amount depends on tackle, fishing style and fish played on the clutch. I have never avoided it 100%, but can do things to minimise it. Like a swivel or pausing when wound in to let the terminal tackle unspin.
I have not used any of the gadgets, but before starting to fish or adding terminal tackle, I put the rod in a rest and walk XX metres of line out on the bank, close the bail arm and physically walk along the line untwisting it - running the twists out the end of the line.
It seems laborious but only takes 5 minutes but it works and I start the day happy!
