Carnk Bolts; capless or self-extracting?

[NEstinkyrider]

I need new crank bolts, size m12.

the two options i see are:
1: m12 capless steel crank bolts for $7.99
2: m12 self-extracting cro-mo crank bolts for $13.99

what's the difference between capless and slef-extracting? does it matter which one's i get? i have an 06 truvativ Gigapipe team DH BB, 68x113

Thanks!

The self-extracting ones are capable of pulling the crank arms off with just an 8mm allen. Get those it's a nice plus.

Yeah, go for the Self extracting, nice to have when your in the middle of nowhere

Self extracting, will make the removal of the cranks easier.

I've always used regular crank bolts. If you torque them down correctly they aren't coming off.

The self-extracting one's looked neat for a while, but my bikes are behind the times (all ISIS stuff) with all the Saint type stuff out it makes no difference in crank bolts.
