Chromoly. It might not necessarily be stronger, but it'll be lighter and the pedal boss won't ever come loose.

Aluminum cranks are sometimes lighter usually when they are racing cranks. Cromoly is definitly stronger. Some cheaper crmo cranksets may not be made as well and may not be stronger however. Cromoly wont scratch or dent as easily as aluminum.

Ok, so if I wanted strength, and weight didn't matter, then I'd go with cromoly? And if so, what brands do you guys recomend for strength and endurance? (what I mean by endurance is how long it will last)

Any Profile cranks and the Primo Powerbite are all great choices in cranks.

Are Redline Monster cranks any good? Their all cromoly, with a 22mm cromoly spindle, so they sound pretty good to me.

There are probably 50%+ of Primo owners that would disagree with you. I have only known about half a dozen people who have ever owned Powerbites.... every single pair of them failed. 2 broke, the rest had pedal/thread issues. I love Primo tires and seats, but their cranks are VERY dubious for quality and reliability.

I should make a comment here about how you don't actually know that he's right, and you're just agreeing with him to fit in, but I'm not feeling very much like stating that right now.

I know because most most of those are for racing not for freestyling

Primo Powerbites, Fit, GT Power Series, Demolition Aluminum, Snafu 13, Odyssey Phat Black Widows, RNC and RNC Lite, and Bizhouse cranks are all made of aluminum, and they're all designed for freestyle riding.

yea but aluminum is less stronger than cromoly so it's not for heavy duty freestyling

The material is less strong, but the strength of the cranks depends on the design and application of the material. Chromoly cranks are tubular, meaning that they're hollow; aluminum cranks are solid (with the exceptions of the Truvativ cranks and Primo Hollowbites, both of which are still strong enough to use for freestyle - one of my friends, a pro from Specialized, has run the Truvativ cranks for at least six months with no problems at all).

I'm not denying that chromoly cranks are stronger; I'm denying that what you previously said ("yea but aluminum is less stronger than cromoly so it's not for heavy duty freestyling") is not true.

edit: Shouldn't you be in school, by the way?

you can still heavy duty freestyle with aluminum but it's more of a risk to break

Yeah that's right, because aluminum will fracture without warning, cromoly should bend first, then break.
