If anyone is up for the challenge, there are some great (IMO) 7's out of this letterbank. HEIRESS, WITHERS, WRITHES, TWISTER. Not sure I want to hand grid all that nonsense though.
Collaboration with my friend Ben, who has recently discovered that he can just message me 15 letter phrases and we'll make puns for hours. This is half my fault, and half his. Comment and tell him he should write crosswords too!
