I need something that has a c of g that roughly corresponds with the base of my thumb that provides the main support point. I have a narrowish ipd that means that porros are usually better than roofs for this reason. My fingers are strong enough for Habicht focussers, but not steady enough, compared to my arms anymore.I have deep eye sockets and find narrower eye cups easier than the bigger kind as I can lock them against my skull.I am long sighted so eye relief is no problem.So what works for me in my septegenarian years for all day use at the 8x30/40 end of things are some porros. For walking, and occasionally finding something to look at, I am happy using my old FL roofs as I can hold them steady enough for short term use. Theorerical performance doesn't count for a lot if you're not physically up to achieving it.We are all built differently, a bit like the old cars I used to fix when young, and it does't matter how nice and shiny that new carburetor is that you just bought, sometimes the old and dodgy one just runs better.</blockquote>
