Interesting post.
I've used the Clevelands ever since I was eligible to get them. I only chose them because at that time people were saying how good they were. I've just stuck with them. You tend not to know if any other clubs are better until you try them. When is the next free rental?
You can't use backspin on Clevelands, I've learnt that from experience. I can do a good flop shot with them. Full swing into the green can be a case of juding the wind and the distance and how much of a swing I take. I can't hit it longer and add backspin. Topspin is okay to roll the ball on further.
I've spent so longer with the Clevelands I'am worried about changing clubs, especially as I'm struggling as a Legend at the moment. However, I might take the risk, it might be to my advantage.
