I was directed by an installer to a website that shows the differences between the beaded liners. See here: http://www.njpoolstore.com/pattern-liners/ . He really feels as if it makes a difference and that I should go with an EW beaded liner as opposed to a regular beaded. Believe me, I would love to save the money, I just don't want to have problems later. Ive had this pool for 11 years and this is the first problem, so I'd say that I've done very well with this type of liner.
