Boge Turbo Gas.  Doesn't matter if I use the lightweight 15" snows from 
my A4 or the much heavier 16" summers (nearly twice the weight), the 
ride quality is still too harsh for the crappy roads in this part of 
Quebec.  It's not too bad when driving in Ontario, but still too harsh 
for my liking.
