PA 2030 with 16 districts
Here is PA with 16 districts if it drops to that. Which is pretty borderline. SE PA + Lehigh Valley + South Central PA hold up well and NE PA and the rurals lose most of the lost seat.
Like your map.
What's weird about Pennsylvania is that the fastest growing part of the state overall is greater Phillydelphia/Septa, yet this region is prolly also most likely to lose a seat due to the current map "bacon-stripping" out the suburban districts from the 2010s map in the name of least change. The 2010s map really nicely nested 6 districts between Philly and the Collar Counties.
Tbf your map cuts both a rural PA seat and a Philly seat and creates a new exurban PA-06 which finally keeps Berks County whole.
