Coolant reservoir caps. S90-V90

The last post made me wonder something; Is it ok to use the black (75 KPa) cap instead of the gray (150 KPa) on a B6304's coolant bottle? I know it is preferred by some for 700/940 cooling systems, but is the same true for 960s? Last night I put a black cap off a 240 on my 964's coolant bottle (the original cap was cracked) and I drove the car about 100 mi today and it worked great. Is it ok to leave it on? Should I replace the gray cap on my V90 with a black one or should I just continue to use the gray one? I can't see any reason to have more pressure then needed unless 75 KPa is too little for the B6304's cooling system for some reason.....

Happy holidays to all!
