I have read some posts about scratchers and started looking into the ones I wanted to put on my sleds... The flexible ones seemed to be the option for me ( I know I would forget the rigid ones and back up with them down) I do not run on my glare ice lakes, mostly trails so I didnt need carbide tips. At $69.99 a pop, times three sleds, I made my own ( I'm CHEAP). Here are a few pictures of them. Used 1/0 jacketed copper.
