Is it ok to open up my range a little when playing fr micro games?

Playin two tables here and it's nice TAG ABC poker I am playing, in position, with a solid range.

But it makes me wonder if I am on the SB with something like 78o, 54o, J10o for example, and I only have to call 1c to see the flop lol should I just call it as I can see it so cheaply? Or should I stick to my proper game? I find myself even folding AJo in the big blind or EP1 as I don't want to be caught out of position, is this the right thing to be doing with the stakes being so low? Profits are slow when doing this and I notice that people who are playing more hands are hitting more flops and profiting more.

I completely hate the micros lol but am being sensible with my BR management. It's such a different game I think. Is opening up your calling range a good strategy in them?

Thanks guys
