Fitting a fluke for a Finis Shooter

[Sammi the Sleepy Mermaid]

So, I looked as much as possible on Mernetwork for information on this specific topic. I couldn't find much if anything at all so I figured I'd start something. IF there is info somewhere, please link for everyone! I've used the search bar and advanced search, etc before you suggest those options :)

My burning question is about laying the fluke over the Finis Shooter monofin. It has some pretty dominant ribbing on the blade and I'm trying to figure out how to lay down my fluke across it without those ribs sticking up to where you can see the monofin between the silicone. I know the silicone won't stick to the blade and I'm just worried if I stretch the silicone fluke over that area, it will fill up with too much water and buldge too much? Is this an issues (I know about drainage and everything, so I'm aware of that). Hopefully I'm explaining this correctly lol

Thanks for all your help if you have any additional information. It's been driving me nuts and I'd rather not make a huge mistake and lose a lot of money over something that I could simply ask about. I've done plenty of testing for other things, I'm just not up for risking such a large portion.
