I'm looking for Cobra f9 driver weights, 18g. Anyone have one laying around they are looking to unload?

Hi all, Thinking about swapping shafts between these two clubs where the shafts are 10g different. I'm curious if anyone knows the approximate head weight of both of these heads. I saw the post at [https://forums.golfwrx.com/discussion/1674956/p790-udi-approx-head-weight/p1](https://forums.golfwrx.com/discussion/1674956/p790-udi-approx-head-weight/p1"https://forums.golfwrx.com/discussion/1674956/p790-udi-approx-head-weight/p1"), but I'm unable to view the attachment. Anyone have any insight here? Thanks,

I removed the standard TS3 driver weight (~10g) and added 10 strips of 1/2"x2" 5mil lead tape (~10g) centered right behind the face. This is basically taking 5% of the mass and moving it forward about 75mm. So I think that means cg is moving forward about 3.75mm (5% of 75mm). Im just experimenting trying to bring spin down a little more. Rough guess based on my golf spy 2019 driver cg and moi https://Not allowed because of spam.com/2019-driver-center-of-gravity-and-moi-report/ I think this will pretty much change the cg similar to the cobra F9 with weight in forward position. I also shortened the driver length to 44.5 (-1") because I was sick of choking up. Realistically I can add another 10g of tape to get the SW back up but I don't want to do that before I try this current setup. If I end up putting another 10g of lead tape right behind the face I would imagine that would really change things. I guess I'm just wondering peoples opinion, if anyone has ever done anything similar, or wondered about this.
