I've so far been able to keep my fav. arrangements from Pa1X pro - Pa2x pro -pa3X 76
Pa3X 76 has served me well for between 1250 and 1300 gigs


I posted last week about the memory battery having seemingly run out of cycles.
I have 3 or 4 keys which are starting to wear through, so..
before I start changing keys and contact strips

Maybe I should just get a 4X?
