The Deep Space is a brilliant kite, just a few random thoughts which might help you get going:
+ It needs 5mph to fly easily (you can fly it in less with practice and a couple of tweaks)
+ Tricks become harder above 12mph by 15 its pretty fast and would be difficult to trick.
+ Smooth winds are best for tricking, ideally off the sea.
+ Buy a new lineset or two, using cruddy old lines with a quality kite is a false economy.
+ IMHO the DS is best one 60-80 ft lines, you shouldn't need more than 90lb strength, but 150lb is okay.
+ Don't run before you can walk ... take offs, landings, recoveries, ground work, then axel, half axel.
+ You'll progress quicker if you stick with the one kite for tricking and get to the beach often.
