I finally decided to get rid of my Innova Starter Bag and upgrade to something with a larger capacity. Despite not having any user reviews, I went with this:http://www.amazon.com/gp/product/B005U7 ... 00_s00_i00
Never heard of the brand before, but the product description was exactly what I was looking for:
Holds 16-24 golf discs
3 dividers inside the main compartment, 2 putter pouches
Insulated drink holder, Mini disc holder
2 Large Outside pockets, Adjustable padded strap
And it's only $30? There must be a catch. It's probably made with paper maché...
