Big shot staggered, the big radius are everywhere. My self am lusting after Martin bros. shockwave but keep that quiet don't want
them spreading like those big radius.

Yes the BR's are common, but thats prolly coz they look so good, but If I were to go again I'd do these------> http://www.paulyaffeoriginals.com/pyo-products-phantompipes.htm

Which girlfriend should I have.... the blonde or the redhead???

Pipes are personal.... get the ones you like the best, as you will be the one who has to look at them everyday.  Just saying.

Just for the record if I had to choose between those two pipes only my vote goes to the big shot staggered.

 these guys make some nice custom pipes with a lot of different options

Big shot staggered  with Quite Baffles in gives a good note and easy on the ears.

Nixon, when i got my Fatty, it had S&S slip ons on it, i loved the look, and the tone, but i hated having to remove the top one everytime i had change to the rear tyre, i went with the big radius, not as gutterall, but has a nice crack to it. But it does come down to personel choice. Just remember, "loud pipes saves lives". Phew, that's pretty profound, i better have a little lay down now, i've spent my wisdom for the day. 

I have the S&S slip ons and yes its a pian in the neck having to take the top muffler off each time a belt adjustment or tyre change is required.
Personaly I prefure the S&S sound and torque and will compremise on the time to take the top muffler off for tyre change, this doesn't happen very often so no big deal.

As for the V&H every man and his dog has got them and I don't think they sound and perform as good as the S&S.

Samson Sidewinders loud and tuned with a tts all good but pipes really are a personal choice my choice was not to follow the pack

just my 2c
