Let us know which one goes home with you!!
While you are trying to get a bike that "fits" you and your style . Don't forget that your riding style will change according to the bike you are on also. I have a RKC but taking into account what you have said the Heritage may be the bike for you. Once you put some time on the bike you will adapt to the bikes quirks (they all have them) and it will feel comfortable. All these bikes have a lot of thought and have evolved into what they are today. In my opinion you can't make a wrong choice but you may evolve to another model in the future according to your needs. A good example of a bikes quirks is the floorboard placement on the RKC makes it harder to back up when compared to some others. The floorboards are so close togather that you don't have much room to move when trying to walk the bike. On the other hand the open road vibration of a "B" motor can wear on you until you get used to it. So don't look at a bikes traits as a negative just as something different because what you consider now as a negative may in the future be something positive and what seems to be a good trait you may grow to dislike .
I hope this helps..

Since the introduction of the 96B balanced engine,the Softails have a smoother ride.No more vibrations in your mirrors,handlebars and in the footboards.My wife even feels the difference after riding all day(as compared to the 92 Evo we owned).The styling of the Heritage should win you over!
A lot of great Input on here,
I would have to echo Tigg's comments. They are both sweet rides. I think you are taking the right approach and and doing your home work.
I was fortunate to have a great buddy who had the RKC and a FB, I rode them both for many miles and hours over a period of a year. I loved the RKC but standing at 6'4"-235lbs with a 34 inseam I just felt cramped on it, not the bikes fault but mine (or my mom and dad!). The FB felt alot more "roomy" to my needs and size, the leg room was there and I felt I was sitting "in" the bike and not "on" the bike comapared to the RKC. Over a 6 month period, My dealer was kind and let me test ride the RKC, FB and Heritage sevral times over untill I had made my mind up.
The Heritage had won me over and have no regrets at all on my choice. As you can see I was looking for comfort over the balanced or un-balanced engine, that did not bother me one way or the other.
It's beenjust about a year (9K) come next week that i have owned it and have adjusted my bars several times and my highway pegs numorus times to find that "just right feeling", but that is all the fun of owning one and tweeking it to YOUR liking.
I wish you luck and safe riding!
