I agree with the idea of needing less than $150 for dialing in; if you're spending THAT much for fit issues, you're getting boutique parts.
But, NOS...gotta tell ya...it's EASY to feel the difference between a 170 and a 175 crankarm. I'll just qualify that for the OP by saying he can do just fine with the 170's, if that's what he has.
