And don’t try and watch zwift or riding videos, it’s hard to not subconsciously steer round the corners!
I used to have an Arion Mag, as above the resistance is just enough to make under/over intervals workable.
Plastic rollers are more ‘rumbly’ than metal ones. It’s a big plastic drum with relatively high resistance. Whereas the metal ones are typically much narrower (and smoother) which tends mean they sound higher pitched (whiring rather than rumbling) but much quieter. More £££ but sportcrafter do resistance rollers. As do Cyclops and Jet-black, both apparently made by sportcrafter but use a different resistance drum that isn’t quite as smooth.
