1800-2200 RPM when cruising at lower speeds unless going up a grade or need to accelerate rapidly. I like the deep, low authoratative rumble and the 107", with the performance combination installed it is not lugging the engine, still has plenty of acceleration. Some of the people I ride with are always reving like they are riding a ricer, now that is extra wear and tear on a Harley engine.
Geez.... With your super performance 107" I hate to tell you but your are putting more wear on it by lugging then revving. Its yours, ride it like you want to, and enjoy it while it lasts...

That fits with my style too. I do a lot of goofing off though.

Mine just seems happiest between 2K and 3K (75 MPH in 6th) when cruising on the hwy. When just crusing around town I always shift around 3K and if having fun she sure sounds good when I am anywhere around 5K shifts!

Lugging is not "just" about engine rpms, it's also about engine loading. Being below 1500 rpm's doesn't hurt a thing in the lower three gears as long as you're gentle on the throttle. If you're in 1st gear, you don't even have to worry about being that easy on the throttle! 
I've had my bike down to 2000 rpms in 6th gear and accelerated away with absolutely no complaints from the engine. It pulled away smoothly with no bucking or knocking. The thing is, I was also being "very" gentle on the throttle. If I wanted more from it I'd downshift but as it is, I'm not hurting anything and I've got 40 years of driving/riding to prove that.
If you like to ride in a sporting manner, then yeah, keep it at a minimum of 2800 rpms. If you're like me, and tend to ride more casually, shifting at a max of 3000 rpms is perfectly normal and acceptable and you won't be cutting the engines life expectancy in half doing it, especially if it's maintained properly.

you're basing this assumption on what??? These motors are perfectly happy at 1500 under a lot of conditions. I wouldn't go 2-up in 6th gear uphill and just roll on the throttle at 1500, but ridden respectfully, there's nothing wrong with keeping your motor in the lower rpm range. Lots of HD motors are tuned to perform better in the lower rpm range.
