I use Pan F, but the price is now such that I have merged and now almost completely switched to Rollei Pan 25. Rollei is closer to Panatomic X. If, and it's a dead if, Ilford should make Pan F in sheets they might be shocked at the amount they would sell. For 120 roll film nothing beats Rollei Pan 25.
I won't even broach 2x3 film, it's available on special order, but only in HP5, I haven't seen any, why can't B&H, Glazer's, or Freestyle carry some once a year? But it really doesn't matter, I just my roll film holders and Rollei Pan 25 or any other 120 roll film.
That's my point, take it or leave it.
