Thanks @Jaywalker. Let me call them and check. I am at 8.5 band IELTS already, so not much scope left there. Let's see if they respond timely. They don't reply to email ticket cases before a week these days, though.
So you are at 435 now and 430 in 3 weeks. CRS is unlikely to go down to 435 for next draw. And also unlikely to go down to 430 thereafter for a long time . So if I were in your situation I would try it out with WES for sure. Also see if you can improve IELTS if you have not maxed out already.
