Though I'm new to this - the 2 lines using your mouth as a vacuum works the best for me.... I've noticed that the longer my tubing is the harder time it is filling the bottle - if I use a piece shorter and boil it for a couple minutes it takes the stiffness away(making it easier for the tubing not to roll back/or up and out creating the stoppage - I watched it sit in the tube until w/one arm I figured something out and there was literally 1/4+ of a liter in the tube when it let loose lol) - So for me shorter line, vacuum line w/mouth, 18g spike(if you do it every 8wks no need for a 16g it'll just Fvk w/your veins over time - so will an 18g but I'm looking to get to a point where a 21g will work - that's what they use during a therapeutic phlobotomy) - you do have help also right? When I have help its smooth... But sometimes it still stops around the 3/4 mark of a liter(sometimes).... Tbh I think your fine - also if it's short of a liter do you finish the 1/4 w/in a few days? Samson just looking for a faster way?
