Everybody has their own experience. Here's mine. When I first set up my keg system I used 1/4" bev hose and 1/4" hose barbs. Got constantly foaming pours. Read up here and learned the 3/16" tubing was preferable. Swapped out the tubing but kept the same hose barbs. When you fit the hose over the barbs, dip the mating end of hose in a cup of boiling water to soften it. I have been very fortunate to have zero leaks in 2 years. I attribute that to the oversized barbs. The down side is you have to cut the hose off when removing it from the barb. I supplement the connection with a worm clamp but believe they are not necessary. It's that tight.
