Why use shallow brake setting?

[guest]

Hi!

I've jumped from 0 to 11 secs of freefall with DBS, because I like the to fly as slow as possible in case of a 180.

Is there any disadvantage by using DBS with slider up jumps?

Morten,
First I'd like to comment that a Deep Brake Setting (DBS) is a relative thing. Often I hear them refered to as some fixed point. How deep a brake setting is relative to the available control range (stall point) will differ between canopies. For example lets say you have a Mojo 240 with a brake setting that is 5 inches (~13cm) deeper than the next one down. This may work perfect for you. Your friend who is 20 lbs lighter will likey open in a stall with this setting. Also 5 inches between settings might be too much for you if installed on a Mojo 260. Try transfering these numbers to other types of canopies and they have even less relevance. This is why Mojos come with a CUSTOM DBS set according to your weight and jumping style. Jumping style refers to how often you use a slider.

This the the essence of your question: DBS with slider? Well assuming your DBS is as deep as it can comfortably be for slider down jumps, it will be too deep for slider up.

One of the major reasons is that your control lines when routed through the slider will travel a significantly longer distance to the risers. This effectly makes the deployment brakes deeper when the slider is close to the canopy.
Deploying slider up with brakes too deep can lead to snivels and heading problems.

The trend these days is to set deployment DBS very conservatively so as to ensure controlability as soon as possible after deployment. Depending on what you have for a DBS at the moment it may be fine for slider up, but beware of the dangers of going too deep. What is deep for slider down may be TOO deep slider up.
