The Trekker bags are something I'm considering for my bike.
Being able to open from the top and also as a suitcase seems like a very good idea.
Can't abide stiff boots, personally.
FWIW I fitted Pivot Pegs this winter. Don't notice a big difference and really don't pay any attention to them at all....maybe that's good. Only time I really noticed them was leanging way back going through some deep mud recently. It's kinda nice to have the peg go with you rather than being perched on the back edge of a non-rotating peg.
