I am looking to replace an ebay blunder with a decent strop. I am looking at the hanging strops at startshaving.com.
2 questions. ....

1) how do I know what size I need? I have a 2" now and have been using an x-stroke. Would a 3" be better and just use straight strokes?
also, do I need the felt? is it a nice thing to have, or will I probably not use it much?

Thanks!!
