Would you recommend the SE255, SE204, or HQ500 for my needs?

There's not a lot of guys on this site that have tried several different cams in the same bike, so in my opinion not a lot of reliable opinions. The dyno sheets on this site aren't very well organized either, making research difficult.
If I had the funds I would tie up a dyno all day and try various cams just to see what the difference is (I just don't have the scratch to buy my own dyno right now).
I'm going with a Woods TW6-6 in my bike Friday, along with a Mastertune and a dyno-tune. I rode a buddy's bike with the same cam and was hooked. On top of the pull the cam has, it sounds flat NASTY cruising around parking lots and low-speed maneuvers. Almost like a Nascar idling through the pits.

One other thing to consider. I have been going with the idea of installing 255 cams this winter to improve the torque at the lower and cruising end. Fuelmoto has come out with a new header that seems to do the same thing. Jamies got some good dyno sheets to show the improvement. I'm really thinking of doing that instead.

Just a reminder; The Fuel Moto head pipes are JUST for the 09 & 10 bikes
I am pretty sure "Mastery" does not have a 9 or 10
But Yes Jamie has put out some NICE!!!!! #'s for just switching head pipes on a 9 or 10 bike

Guys- Very interesting topic. I've got a 2010 Ultra Limited with 3000 miles. Here are my impressions. I bought the limited for the 103 engine, having my last by an 03 CVO Road King with 50K trouble free miles, w/ great power. The 103 pulls noticably better than the 96 riding 2 up on grades, but still needed a little more low end and sound. I went to V&H power duals and monster ovals because I have been advised that they are getting the best HP without going to 2-1 on the 09's. I went with a PCV instead of the race tuner for 2 reasons: 1- the power duals were not available with the new O2 sensors, and HD wants too much $$ for the dyno/racetuner combo in my area. I was fortunate enough to be in Dynojets backyard and volunteered to be the test bike for my engine combo for the powercommander. They did an autotune and then a fine tune. The bike runs great but the HP is low. 78hp/95tq. Torque is as flat as Kansas. The tech at Dynojet suggested cams as the next step without tearing apart my new motor, as a good bang for the buck. I'd like to be in the mid 90's hp and right around 100tq. For the couple guys who have 2010 limited's, they come standard with automatic compression releases, and a good PCM module or race tuner should eliminate any possibility of hard starting, pinging or heat issues. From what I am interpreting, the 255 cam sounds pretty good. But I would like to see some numbers.

Don't be fooled by a "pretty" dyno sheet.
What you see on paper is ONLY a snapshot of what a particular motor did, on a particular day, on a particular dyno ~ at 100% throttle, WFO. Bet ya don't ride that way too often, eh?
Very often, a motor with a great dyno sheet may will not run or "ride" as well as one with a seemingly less attractive "dyno sheet". If all ya wanna do is brag about something that might sever better purpose wiping crap from your crack, then the dyno chase is for you.
Based on the original description of riding style, the HQ500 would best suit his needs.
He did not say he was after all the torque he could get at the bottom. He indicated that he rides a bit more aggressive and may be prone to revving a little higher than 255 might perform "optimally".
Just another opinion ... take it as you wish.
Regardless of what you select, as long as you have it PROPERLY tuned, it will run and RIDE superior to what it does now. Furthermore, if you choose something like the 255 and have it tuned correctly, it will be better than what you have, you'll probably be happy and you'll never know how much better (or worse?) a different selection may have been. As such, it really doesn't matter that much anyway.
One more time, because it's important, your tune will make or break the end result.
... did I mention the HQ-500?

I originally posted this with several choices in mind. I'm now down to the HQ500 and the SE255 (leaning towards the HQ500 though). They both will work with my riding styles since I vary. Now that I'm down to two, I'm just keeping an eye out for the best price that pops up, and that's probably going to be my deciding factor.
