... However, grinding gives you a better edge that lasts longer than honing...
My personal experience tends to make me disagree with this statement. A honed edge is by far a better edge, its cuts cleaner and with less effort. I dont think it lasts as long as a solely ground edge but its pretty close and takes the same or less time to renew. And yes I keep my Wolverine set to the tool I am using but honing is still faster in my opinion.
As to the OP if you are getting heat your tool isnt sharp enough. I do all my pen turning with my 3/4" spindle roughing gouge and touch up the edge between blanks. It cuts cleanly on everything that I have tried, albeit I have not tried Trustone or some of the harder blanks.
Again this is just my personal experience and I am not intending to start a he said, she said mine is bigger, better, badder war just offering the opposing opinion.
