On bicycles there are a few nuts that are very large across the flats but very thin and require fairly substantial torque, so they're easily rounded off. The best tool for them is a large adjustable wrench. Play can be completely eliminated before applying any force.
I have a few Crescent wrenches too. They are handy. I also have a couple of good sets of double ended wrenches with a wide range of size, in Metric, Imperial and Whitworth. As you are, I'm very careful to choose the right tool and size, before I start working. I have found that if I don't, I usually cause myself a whole heap of unnecessary work.
I've learned a thing or two about tools in my life, which I could of learned from my grandfather or father much earlier, if I only listened to them, when I was a kid. But I didn't. I had to go and find out myself ....usually by trial and error.
When I've bought either hand or power tools, in about the last 30 years, I've always bought the best I can afford.
Before that I bought the cheapest I could find, and from poor experience using the cheapies, I determined I wasn't getting any bargains, just a lot of frustration and literally 'screwed' up work.
