I would not mess with a Deep Space bridle, unlike many kites rushed to market the DS was tested and tweaked to perfection - it was not a quick process, especially for us waiting for them !
If you want it to fly lower - here are your options:
.1) Remove the tail weight.
.2) Remove the upper spreader
.3) Use lighter lines
.4) Use shorter lines.
I like to fly the DSUL as a street kite ... on 20 or 30' lines. I've been the only kite in the air at festivals when everyone was grounded and grumbling.
