It definitely depends on the client. If the team is crunching to hit a deadline and I'm saying, "Sorry, I'm at my weekly cap, so I'm leaving early today and won't be joining you this weekend; see you on Monday" then I'd be surprised to be invited back for the next project. I certainly wouldn't expect to be given any important work. But I also feel you on time tracking, so I think a weekly rate is great if the client's culture is such that there's a natural cap and it's a good match for the work.
