So, I bought some Motopak luggage available from a BC distributor, via ebay. I waited around for a few auctions and got a really good price. A lot cheaper than what you would pay in the local shops.
I got the GTS-60 saddle bags and the mid sized tank bag. I just used them both on a trip around the Olympic peninsula, at some high-ish speeds. The bags were rock stable, well made, have their own rain covers (which I did not use) and were otherwise great. Good construction, cheap prices.
The only bummer is you have to insert the internal supports yourself, which can be a real pain in the but, but it all worked out again. I felt very comfortable with these bags on the bike.
some pics to follow tonight...
