Don't fear the meter, ha, ha.
If you can handle the meter on your Clevelands, you can probably handle anything. They are only slightly slower than the top R11 and Burner irons.
I was/am meter challenged. I remember hating the meter on the Starter set, and loved the Starter Plus' slow meter. After a few months, moved up to the Raptures, then the G10s, and now the R11s, and don't regret it.
If price is a consideration, you want to go ahead and get the best clubs you can, despite the meter.
