That one is easy, you don't suggest any modern style of aid. Ok got it..... I simply have no idea what you are trying to say by those two sentences. They contradict each other. Let me show you my line of thought.
Sentence#1 I don't suggest no modern style of aid.
Sentence#2
Here is where I have some trouble. Are you saying that you don't suggest any modern style of aid because it's beneficial, or in spite of it being very beneficial? Now you see my quandary, Why would anyone not suggest a style of aid that they thought was beneficial? The logic simply doesn't follow.It's often very beneficial!
Perhaps the double negative was confusing. To eliminate the double negative, the sentence translates accurately as: I suggest a modern style of aid [is beneficial].
