Try one with out any adjustments and see if you are happy.
When doing the FWS and PC blocks I sometimes had to do that and it was OK .... yes it's bulky, but a whack of the hammer, a spritz of water, hot iron and some Best Press ... and they came out flat as a pancake!
If you've done all your blocks already, it's probably too late for you ... but if not, you might want to look at the PP patterns and see if you can re-arrange the order of placement to get the seams lining up the way you want. I was often able to do this, so long as I remembered, sooner, rather than later!
