Save your cash . I'd ask why are you considering longer arms ?
My experience with longer cranks(up to 185mm) is that they didn't live up to the promise the crank length theories based on leg dimensions claimed. Theories are theories after all. The opposite way works for me. Foot further forward of the axle and much shorter arms(150mm) works brilliant for me. Ease of leg speed and leverage. I'm not alone in this discovery of course, it's just that it doesn't fit into any of the en-vogue formulas, so few bother to challenge it.
