hey all thanks for comments. i guess part of me asking is that this classic combo does feel a little 'old fashioned', but it is super versatile and the shopsack is like a perfect fit for the basket. i just pass all these cool looking front bag options!
i may be exaggerating a little bit the shimmy and wobble, its hard to nail down but sometimes it feels like the load will start shifting and osciliating, its never out of control but it does make me sit-up and pay attention--i can feel 'something'. John, makes a good point, this bike does have pretty serious front wheel flop, so it could be that i'm feeling too. the basket is held on at the moment with a mix of zipties and straps, but maybe i can stiffen things up with some cross support? How are people attaching the baskets? Re: the perilous part, i know that Riv/Nitto are very conservtive with both weight, and warnings about using the racks as support for a handlebar bag instead of a static load. and i am as nuts as all of you, when i had a platrack on this setup i carried a car batttery and watermelon in my 139 basket! Stephen, which front rack are you using for the 139? Again thanks for all the thoughts, will try to be more aware of weight vs wobble feel. i've been riding to work so its pretty much the same load, but will focus on it more!
