TrekJeni - The new Light Actions are scheduled to replace the X5 pedals. These are very easy to use - clipping in and out. I got to play on some at Interbike. These won't work on Lynda's mountain bike shoes thought - road shoes only.
My vote goes for Speedplay frogs too
I got mine in June and love them. I switch out between road shoes and MT bike shoes depending on the trip and the weather and they fit on both types of my shoes
It's about the journey and being in the moment, not about the destination
