i'd have to agree with hawker. my first TC was an EVO III SE so I had to buy the EVO IV when it came out. My buddy has both and he likes the 415 better, but he hasn't ran the 4 half as much as the 415.
since i was already familiar with the shaft, i didn't want to muck with belts. if for some strange reason i have $500 sitting around, i would buy the 415 too.
hope that makes the muddy water more muddy!!!
