Do they work together? Thinking about putting some of the 14 din fks rossi binders on my new lifes. I've heard mixed things about using trekkers with the older model fks bindings -- like the heel on the base plate of the trekker hits the heel piece since it's so tall - wondering if this has been fixed with newer models.
No you don't even have to have the bar up if you set them up right. I've done it with two different pairs of FKS with two different boots and both times there was a gap between the boot heel and the dildo (see the shot below). Wrap a load of duct tape around the metal bar so that your brakes get engaged when the Trekker snaps in (gives you a duct tape supply on the hill too).
