i used to automatically re+re the OEM wipers with aftermarket units when i bought a car. my go-to aftermarket wiper was Bosch Icon. a very good blade.
i did this with the G37 as well. however, i then switched back to OEM insert refills and haven't looked back. at ~$6/ea you can't beat the value and they perform very well. the OE style of wiper arm is retained and they can be changed more frequently as needed for a very low cost.
