Old style Madden packs for newbie bike packing setup?

[gabbard]

I am planning on taking my first bike packing trip this summer.  This will be a total new entry to bike packing for me, so I am trying to keep the initial costs down.  Also, to kind of ease in to it, I will be doing a trip to several 10th Mountain Huts in CO, so don't need cooking equipment or shelter.  My question is about bags:  I have several Madden packs from my previous bike tours many years ago.  These are the kinds that attached to Blackburn racks mounted on a touring bike, hardtail MTB, etc. and I have used them for several tours.  What would be the negative of using a set of these on a rear rack, with a more modern bike packing seat or handlebar bag to add to the storage?  Perhaps not the most stable, but would this work for a beginner setup to get me out on the trail?

Thanks!

Racks and panniers tend to encourage people to overpack and can shift too much weight to the back of the bike which can negatively effect handling.  They also can make it harder to push the bike through unrideable terrain.   If you pack wisely and try to balance the load by strapping some of your gear to the handlebar they'll be fine for a hut to hut trip.  Have fun.
