No no no, these people are misleading you. If you are beginning 4a, you need a small yoyo. Seems strange, but they are seriously more easy to catch and whip. You should so totally get this, http://yoyoexpert.com/product/yoyofactory/mighty-flea/
Okay just kidding. For beginning, Aquarius or F.A.S.T. Offstring. I know you don’t have that on the list, but its good, its big, its rubber.
Bigyo, bigben, kickside and speedmaker are not good for 4a for beginners. Why? because they are plastic, and since you’re a beginner, you’ll be throwing plastic yoyos at tv’s, windows, bottles, badgers dogs and cats. Bigyo and bigben are good for 4a ONLY when you are good at it already.
