Dragging luggage is definitely my fear - I know the pegs are hinged and will fold when I scrape them, combined with my foot being there I can feel when it happens and know to slow down a bit. But if hard-luggage scrapes, I worry that with nowhere for it to go it will take weight off the rear tire and result in me sliding out of the corner. The hinged peg-feelers are my safety barrier and I would very much like to maintain having that after I mount luggage to the bike. I haven't adjusted my rear preload from stock yet - is there a good/recommended way of measuring the suspension sag with/without load?
And I am aware of proper body positioning while riding through the corners - when I find a nice windy bit and push a little, I'm leaning a lot more to the inside than just head over the mirror - I hang off the handlebars to the inside, with butt also off to the inside and just my outside leg hanging on the seat. For reference, last year during a 9-day trip we took a road called the Flowery Trail Road
that is the most fun piece of road I've ever ridden. Virtually all of the corners were marked with 35mph warnings, there was no traffic (didn't see another vehicle on that entire road), and perfect conditions (great weather, clean brand-new smooth pavement, etc.), and I averaged ~160kmh (100 mph) through most of those corners (and didn't scrape any pegs in that section either). Also - I don't advocate others do that, never ride above your comfort level, don't push yourself to keep up with others in your group. But I don't have a problem with having a little fun when conditions are right and the risk to others if you screw up is low (no 100mph playing in traffic/cities please). If you are in that area though, I do highly recommend that road.
So - back to the topic, my second choice for bags were the Trax alu-boxes. I lose the modularity of being able to use just one of them as a top-box for commuting, but they do bevel the lower outside corners of the boxes for more clearance while leaning. Can anyone comment on whether they have any impact on lean angles on the bike?
