Brooks B-17 isn't breaking in, how to accelerate the process? I have two bikes with Brooks B-17 saddles on them: 


My full-frame touring bike: The saddle has a nice patina of age, having been used for several tours and some commuting. 
My Bike Friday Tikit folding bike: This one doesn't get used for rides of nearly the same length, mostly because I can use the bike with the nicely broken-in saddle. Also, this bike has a more agressive posture than the touring bike, and I keep more weight on my legs than on the saddle; could this be part of the reason the saddle isn't breaking in? 


I've been using proofride about every six months on both saddles. I've had the Tikit for over a year. 

The question: Is it possible to break in or age a B-17 more quickly? Right now, it feels more like plastic than leather, and isn't comfortable for rides of more than ten or fifteen miles. 

Alternately, would attempting to age it and soften the leather damage the leather? Maybe a B-17 is the wrong saddle for this bike?
Wouldn't the simplest answer be to switch the saddles between the bikes?  You'd probably end up using the less used bike more and the less broken in saddle more too.
