Once you go over 20” I dont think people realize how much it takes to keep adding an inch bigger. My best I did 2 liters of D5/.9 and blew up to 26”, but that’s a far cry from 28”!
You are right. I can get to 26 quite easily now.
Going bigger is another story. After 26in it takes about 1.5L D5 to gain an inch until you get to 28in then it can take up to 2.5L per inch gained.
The biggest I have ever been is 28.5in and it took 1.5L to get the half inch. I could not continue. My goal is to hit 30in some day.
My estimate is it would take 12L to get there. Wowza.
Seems like the solution could be n2o inflations. You could use them to stretch your sack to the max and deflate relatively quickly just to keep growing. One 45 minute session at 5 psi will cause my whole sack to be sore and flakey for a few days.
