I'm working on a credenza design and am planning to use Blum movento slides with Tip-on push to open. Does anyone out there have an experience with the different "push" strengths? I'm trying to decide which I want to go with. The credenza will have 8 drawers with the lower 4 storing my vinyl record collection so the L5 is definitely going to be used. The top 4 drawers will be shallower and I'm thinking of the L3 would be fine. The drawer sizes are 14 w, 18L, and either 13" or 6" deep and possibly 1/2" ply bottoms.

If you have experience, how powerful is the push and will an empty drawer rocket out if I go with the stronger L5 Tip-on units all around? or will I find the L3 somewhat anemic.
