I have some, they are pretty light and they were kinda flexy but I am a biiiig guy, the are actually made by RPM and they are sold as FSA cranks as well

Thats kinda my feeling, I think people generally hate on them just because everyone else does, just like most other things on here. I think the FSA version are usually marketed as BMX cranks

man looking at that price i am super tempted to get them to replace the stock ones that came with my pista. i think those are pretty slick looking. without hijacking this thread, could anyone recommend a decent chainring? (preferably 48 tooth)

what size do you guys have because they range from 150mm all the way to like 165 i think. what are the pros and cons of shorter (or longer) crank arms?

they make 170 too i think. maybe bigger.
the only benefits are having smaller spins so your legs don't have to move as much, and less toe overlap and pedal strike. that has more to do with frame geometry than a smaller diameter spin though. 150 are basically made for kids with short legs. 165 is a good size.

i have some on my fixie. i think they are usually marketed as bmx cranks. i run the 170s
you generate more power (by having more leverage) with longer crank arms if you bb is lower to the ground you would want shorter cranks to avoid pedal strike and toe over lap. luckily having a tr-frame i have a high bb and no toe over lap.
i run a 40tooth rocket ring in mine, but you have to be carful to find the right crank arm bolts to go into them
plus i ran them on a pedal cab with no issue for several months.

I have a pair, and I like them. Then again, I've never owned a "nice" crankset, so maybe there are things that I just don't notice about them because I don't have a point of reference.
