Would switching from Hybrid to straight BG be good enough? Or would I need more than 400?

The neighbors outlet is a screened in 4.5" culvert running between the two ponds. I never even noticed it till this last rain we got and I saw a nice current coming from under the south bank. I actually own that corner of his pond where the outlet is.
