Impressive lifting mate. This back to front thing is interesting. I can see the merit in it.
I have a Toro lever and it has become very distorted and twisted within 8 months. I will be interested to see if yours does the same although I have never spoken to anyone who has had the same problem. Lever is definitely great though. Saves so much time mucking about.
With the nose tork, open it, hold it down at your belly and slowly raise it up until you start getting a really good huff of it. Inhale as deeply as you can. Good idea to close your eyes too as it makes them well up almost instantly.
