I just installed TW-555 on my dyna. Cams are really good. I don't feel that I gave up anything down low and I got much more from not far off idle to my 6200 redline (sorry no tach yet). These cams to not fall off.
My dyna is a lighter bike but I these cams seem to be better almost everywhere without falling flat.

103" with 570 cams
I went with 570 cams when my 103 build was done and couldn't be more pleased.
Personally I wouldn't change cams without having head work done. Just my opinion.
Ended up with 109 HP / 122 TQ after the Skip Grove Stage 2 Silver Bullett Heads were done.

And, your comment about "quiet" (I'm assuming valve train noise) is good with me. I had a motor with Andrews 570's and thought them to be noisy.
Oh, already have Jackpot headers with SuperTrapp FatShots (18 discs and closed ends) and V&H air cleaner.

if you plan on building your motor with more compression, then the 255's wouldn't be such a great idea. the reason is that the se 255's create a lot of compression with just their install. i'm very happy with the se 259-E cams, it's a great combination for my build. .579" lift, and the bike runs very strong from off idle to the 6200 rpm rev limiter.
I bought a set of new SE-255's but am having second thoughts about installing them. Discovered the Cycle Rama 575's just a few weeks ago. If I see enough good results and satisfied owners of the 575's, I'll but a set of them, instead and put the SE-255's up for sale. All I want is a little more oomph at highway speeds (2,750 - 3,000 rpm) for shift-less passing and long inclines against the wind. Don't want a hot rod. Don't want pinging, kickback, or other issues that people describe with hotter cams.

All of you guys swapping cams out and leaving the stock valvesprings, what kind of lifter/valvespring life are you seeing? Woods usually has fast jerk rates, which is great for getting area under the curve but not so good for durability. Has anybody run something like an SE255, 204 or Woods 6-6 in an otherwise stock 103 for 30k miles with no issues?

I've just about decided to sell the '255s and wait to see what people report with the Cycle Rama 575's. From what I've read, I think they are probably perfect for a strong touring bike. I want to be able to slightly twist the throttle on I-25 and easily maintain 75 to 80 mph, that's all.
