I am wondering if any of you have a size 11 or 12 shoe, have a DUI TLS350 or equivelant with the turbo soles...not rock boots.....and XL Jetfins? I have two questions. First is will the XL Jets work, or do I need Turtles. Second, if they will work, what size straps do I need, specifically the Halcyons. Let me also say that I cannot measure my foot in the fins with a string as I dont have the suit here from DUI yet, I am trying to get ready for it. Also, I just sold a DUI CF200X with rockboots and turtles, but have NO experience with the turbo soles. I am hoping it will allow me to use my XL Jet fins. And lastly, I know I will get flamed for buying the Halcyon straps and that you can buy the generic ones or make them....I am a machinist by the way...but I do like supporting Halcyon when I can and the straps ARE sweet. Thanks for any advice you can give .
