I did that too...took a sabbatical from them to focus on squats and rest my back, as my back was starting to get regular stretchy feelings especially with the regular 1RM attempts. Glad I did because my squat has come up a fair bit from what it was and now I've reintroduced deads, they are much lighter but I have heaps better form.
Always good to reset form once in a while and take a break from a particular exercise, particularly when you're not competing in lifting or anything. Sometimes it's as good as a break from the gym.
