I am planning to replace the original cylinder of my HW100KT. Looking for an affordable lightweight tube.

- A+M cylinder, well known, no valve fitted keeping the tube pressurized when unscrewed, bit more expensive
- Fenton cylinder 283266679414 which weighs only 224 g and has valve
- Rat Works cylinder 323597515671, 400 g with valve

My favorite is Fenton, lowest price and lowest weight. Anyone has experience with these 3 models?
