This is really the first greater-than-less-than puzzle I've worked. I get the basic idea (that the arrows point to the lower numbers), but there must be some techniques that are unique to GTLT that I haven't discovered yet.

I don't know of any software that can handle these puzzles, either, so no way of getting any hints. (Unfortunately, even though I can import the candidates into Richard Piarina's SudokuSolver and print/save the puzzle, I can't put the arrows in there, much less use the program to solve it.)

This is supposed to be an easy puzzle, but I've made very little headway on it. Here's the puzzle and what I've done so far (along with LCs on 1r2c2/r2c3, 9r7c1/r9c1 and 1r8c8/r9c8). Any ideas on how to proceed?
