SC Tools were believed to make the experience 8x instead of 4x. That, in a way, they do, but instead of taking away 1 use from the brawling glove, it takes away 2 uses of it. This means your brawling glove will disappear 2x faster, but you will still get the same amount of experience pretty much as if you hadn't used the SC tool. It is completely up to you to decide wether or not to use SC tools. For things like smithing, you're in the wilderness for usually under a minute at a time -- meaning when you tele out and bank, you have not gained any hotzone, so you can do it with that to save more money. Adze, lobsters, neitz, etc. all look to be better things to use. Also, you will not gain as much hotzone if you use SC tools... and if you get more hotzone, you could get more brawling gloves and more profit! Up to you though. In terms of efficiency, usually just using regular methods will be way better, as you don't have to sacrifice any time to playing SC. taken from viewtopic.php?f=113&t=780792
