i use tower e cono cote med heat. it's cheper and i have grate success with it. if I do get a wrinkle in it i turn the iron just over med run it over again and most wrinkle's disappear. it conform's grate around corner's .one tip i can pass on to you.run your iron over the wood just be for covering.it release's the gases and air trapped in the pour's of the wood.do the bottom of the wing's first and pirce a pin hole it trapped areas of confined space's so it dose not push air threw the wood pore's when heated.
I'm by Farr not a pro and im not trying to portray to be.
P S Georgie i hope you got the pick that go's with the slotting tool it really a time saver if you use the gage that con form's to your hinge's
