Glad to hear you're enjoying the Brooks. I have a Team Pro on my road bike, and a B17 as a captain saddle on our tandem. The B17 lived for a couple years on my touring bike (converted mtb) prior to buying the tandem. As I use the touring bike on the rollers and trainer, my *** is getting ready to order another B17 for that bike.
Regarding the proofide, the advice I heard was to apply it more frequently (once every couple weeks) when you first get the saddle, then after a couple months you should be ok only applying it very infrequently.
The shower caps they give you in hotels work very nicely as saddle covers
