I am currently breaking in my 2nd Brooks now. My first, a honey Brooks Flyer, which is now on my Trek 700, was comfortable right from the start. I applied proofide regularly and after 3 years now it may still not quite be broken in. But as I said still very comfortable. My newest, a standard B17 well, my butt's telling me it's not so instantly comfy. Odd since the Flyer and the B17 are the same only with springs on the Flyer. But still far better than most plastic saddles. Once the weather warms more I'll probably put some proofide on the B17 also. I agree they do feel better in warmer weather. And yes they are tilted up in front. I've had the best luck tilting them up rather severly and then as they break in, lowering the nose a bit. I can feel the nose with my tender bits, but it's not uncomfortable. Finding that sweet spot is key.
As paydirt said it's as much breaking in your butt as breaking in the saddle. Give it plenty of time.
