Sidi shoe buckles: have they changed over the years?

Update on the above: this wee trick seemed to work fine when trying it out in the house, but then i put the shoes on and wanted to tighten them up. Once the straps get under tension, the ratchet doesn't grip the straps sufficiently to pull them any tighter. You can push the straps in further with your other hand and they will then stay securely in place, but it means you can't tighten your shoes whilst riding. If you can live with that it's still an okay solution, but i'll be ordering new straps after all. 

Gotta love the net: just happened to come across the tip below, which seems to work. 2 minute job to modify the buckles. 

"Looking at the new buckle from the strap entry point - you'll notice two tiny plastic tabs blocking entry of the older Cinturino strap(same exact width). Simply lance those tiny tabs off with a sharp blade and the older strap now glides in and ratchets securely just like new!"
 

Just my luck! I hadn't even realised you can change the straps as well. Will be ordering straps then, thanks
