EVO or Twin Cam

hello municipality, I am meant to buy a new fat boy model 08`. the main reason is that my 99 fat boy evo has too little steam and an upgrade of my opinion is not in any relation. there would be 200 rear wheel, 1600 hundred motor etc. the evo would remain an old motorcycle even after all modifications. I drove the 96 twin cam today probbe. he has already significantly more steam. but the exhaust sound.there you should do something immediately. what do you think about it.evo keep and with your peculiarities life or step into the new harley age dare. I am still a bit divided. I am looking forward to your postings maybe you can help me with my decision. so long fatty
