Got NSW invite today...want to wait for 189

Hi experts, Job code - software engineer Points 70 for 189 75 for 190 I have got NSW invite today and have to lodge visa. I know that 189 invites will open in July.. Want to wait for 189. Please let me know how to go about this ? Shall I wait till July to lodge visa for 190? Or atleast I shall go through medical and PCC ?
I would suggest to go via sc190 route. You will get approval in 2-6 weeks, in the best case scenario you might be able to get a direct grant by the time you will receive sc189. :) You will, however be limited to NSW for period of 2 years.
