Sounds like you need to learn more mix-ups for your bomb strategy. Here's a few:
-Full hop bomb pull into an arrow cancel. It's a good way to poke aggressive players trying to charge you from the ground. Or full hop bomb pull into your second jump, z drop your bomb and recatch with a fast-falled nair.
-Learn how to do aerials with bomb in hand. You have to quickly drop the bomb with z then recatch it as you are doing any given aerial. I'd say it's a key strategy for countering aggressors. Scizor is great at using this.
-Foward smash with bomb in hand instead of trying to throw it (I think it's called a bombsmash? I can't remember)
-Use jump-cancelled bomb throws sometimes instead of bombsliding. It allows for better precision when throwing bombs, and it has different spacing to throw off opponents.
-And there's a lot more. Check out this thread for more mix ups you can do with bombs:

Also, what language is your signature in? I tried running it through google translate, but it looks like it's in at least three different langauges, ha ha
