Hey all, I have few questions: 1. Which one is recommended, the plastic tank or the steel tank? 2. Which is better, plastic reel or stainless steel reel? 3. Is it better to go with a tank that hold one 120 reel or 2-x reels? so can i develop one reel in a two-120-reels tank or it is better to develop one reel in a tank which hold 1 reel? 4. If getting a 2-3 reels  tank, can i develop 2-3 film rolls at once without issues [same process for the 3 rolls]?
