You don't need Tech 1/Tech 2 buddies to prepare for Tech 1. Do lots of minimum deco ascents and practice your fundamentals skills until they are solid in midwater with only your team for reference (to ease into this, shoot a SMB, tie it off somewhere on the bottom, ascend on the line to 6m, clip a double ender into the line for reference and do your V and S-drills there) and T1 will be a breeze. And don't forget to practice the rescue technique.
