I'd leave all the existing tie downs where they are, and add tie downs farther out on all the branches to pull the ends down to just a smidge above level- although, you may need to uppot before you have room do that...For the Gel 1, the end of the branch on the right side of the top pic needs be lower than the rightmost orange pipe cleaner for LST to be effective.
Leaving the existing tiedowns where they are will keep the branches from bowing upward in the middle when you pull the ends down, and keep them growing as straight as possible..
If I'm misunderstanding what you're trying to do, then nevermind...
