Hello, I have a job coming up cutting a fair amount of 3/8" plywood. I am curious to know if it would be worth switching to a 100mm focus lens. I do have one available, however I have heard that with the Rabbit laser, I will need to drill the hole in the focal head a bit bigger in order to use it without losing power. My biggest question is will using it allow me to cut faster than my 2"?

My second question is whether or not anyone has modified the focal head and what is all involved? I have tried to find the article on Rabbit's website, but the file is not available. Besides reading a guide, there is often more knowledge in a multitude of counsel. Thank you for your time.
