I need to build a fence for a garden that is enclosed in concrete walls. my fence will look something like 
Since I am building this on a concrete wall I want to figure out the base base I can use to secure the fence. While I browse Simpson Strong Ties website I see they have the EZ Base. I thought this was my for sure answer as my fence height is roughly 5' and I do not need this for any type of wind resistance.

I put a call into Simpson, and their CS rep recommended I go with the ABU44Z style.

Does anyone have experience with either? For some reason I feel like the EZ base would be a more secure option though I like how the ABU keeps the post off of the concrete.
