are they "ball" type to?
What do I want?
Steel ball type ~ $25 a set
Alloy closed ~$100 set - but not clear if they are ball type
Alloy open ~ $75 set - look tapered to me - evil bay
Alloy OEM (claimed) ~$160 set - evil bay look like ball type
Who / what should I get? should I buy steel for now and buy alloy later?
Your insight is needed
