This also depends on whether it is a single or double solenoid because they usually have different pilot pressures. The SMC SY3000 (we use them too) has a min pilot pressure of 0.1MPa (~15psi) for the double and 0.15MPa (~21psi) for the single. We used a double for the shifter (regulated to ~25-30 psi) and singles everywhere else (to save SPIKEs).
Back to the roll pin topic, I believe we broke the initial pins in both of this year's AM shifters before shipping the bot. We never broke pins in any of the AM shifters we used in the prior 2 years. We replaced with higher strength pins and didn't have any more problems. I know 1503 broke their pin at FLR and used our stronger pins to replace (dont know how that worked out past FLR). Maybe a lower quality batch of pins this year or just too much shifting into Overdrive.
