3/16 vinyl has resistance of 3lb. per foot, so anything over 50''(13lb.) with the rise will make the pressure to high and will over carb the beer.1/4''vinyl is .85lb/ft. so 10' resistance is 8.5 lb. plus lift of about 4' at 1/2 lb./ft is 2 lbs. so total is 10.5 add 2 more ft of 1/4 or 9'' of 3/16 and you end up with about12.75 resistance . at 36-38 degrees this is close to what most beers run.
