Pain in the soft tissue area is not a good sign and will get worse over time. It can even cause damage to the area, so you definitely want to avoid it. No amount of breaking in of the saddle will alleviate the pain in the soft tissue area.
For a Brooks it's best to start with the nose of the saddle level (I got that advice from BSG) and work it up or down in tiny adjustments from there depending on if you're sliding forward or back. I find I like it with the nose pointed slightly upward, but depending on my position on the bike and if I tend to wear padded shorts or not with that particular bike the tilt is slightly different. The B72 (same top as B68) on my touring bike is tilted a hair lower than my other bikes because of that.
I just put a B17 on my Xtracycle and the leather on it is thicker and harder than the leather on the B72 and B18 that I have on my other bikes. It took little to no breaking in period for those saddles, but it's going to be a while before my sitbones don't feel bruised after a ride on the B17. I hope it doesn't take 1,000 miles or I may abandon for a B68.
