If you're running comfortably in x-talons then it sounds like you're well on the way. Roclites are probably less stable than x-talons (although I don't own any roclites so can't be 100%) because x-talons are very low to the ground. Try the f-lites and see how you get on. I'm at a similar point myself, my current road shoes have died and I only have racing flats left so I'm, thinking of using them permanently for road work from now on.
