Sure, softer tips flatten sooner. I don't go to the extreme with the LePro. I always select a harder LePro out of the box. My point is that I've bought and used $10-$20 Moori tips for years and the LePro ended up being a tip I shoulda stayed with @ 50 cents a tip.
My phylosophy concerning tip maintenence is this. Your stroke "conditions the tip" to your partucular stroke, naturally over time. When you continually shape and mess with a tip, that's your tip-man's best dream. If a tip ain't mushroomed...just play with it. sid
