My 2nd roll's negs as you saw two threads up are way too thin....hummm

Shot at 25 dev Xtol 1:1 for 8 mins. Think I went the wrong way

Should have gone 25 ISO and maybe 13.5 or so ???

The initial roll at 50 for 1:1 Xtol for 13.5 mins were pretty thin too but the blown highlights made me think shoot slower but cut the dev. Anyone getting thicker negs?
