I'm in exactly the same position. I'm not at a tipping point. I've already been tipped! Just can't justify the cost with all the problems attending regularly.
It's worth bearing in mind before you give up your ST, at least if in north, that it's almost 2 for 1 if you by on individual basis such is the extraordinary cost I've incurred when buying additional ones for friends and moving to another part of stadium of equivalent viewing.
So don't be too...
