Replying to Full Tilt Tongue sizing up

Does anyone have experience throwing a XL tongue on a 26.5 FT boot? When I originally ordered the tongue replacement, the sizing indicated I need a medium tongue. However, I came across some stuff on the internet that said Seth Morrison recommends the next size up because it has a taller shin and more wrap around. EVO did not have a L so I ordered an XL to see if it would work but I'm worried it might be to big. What do the steeze lords say about this. Also, if anyone has a 10-flex tongue for sale, I am very interested. I only went from a 6 to an 8 because stock is limited.
