Would it be wiser to put cards and sleeves upside down in toploaders?

I'm going to send a handful of late 90s inserts/parallels to COMC in top loaders including a 98 PMG and a 99 Fabulous 40s Extra, but am wondering if it is better to put them and the sleeves upside down. I just know every now and then cards I buy on ebay end up slipping out of the sleeve and the only thing completely preventing them from falling out is if there's tape. I guess the downside (no pun intended) of putting them upside down would be that it might be harder to take the sleeve out of the toploader that way.

If your worried about the cards slipping out of the penny sleeve and top loader. Put the whole thing in a team card bag.
