I am building new vanity cabinets for my master bathroom. I used to always use epoxy coated self closing slides that I buy in bulk from Woodworker's Hardware. They work well, but lately I have been using the CompX Waterloo Full Extension 100lb slides on my projects as i like the ability to get into the back of the drawers and it lets me make the drawer fit tighter. The prices are great compared to most other brands and I have never had a single problem with them. I also like the fact that they seem to have less play in them compared to the epoxy ones, thus making aligning door and drawer fronts easier for my modern designs.
So I was checking my stock and found that I have an ample supply of the epoxy glides, but need to order the F/E for this project. It got me thinking on what others find to be their favorite. So what do you use most often and why?
