Looking to make a few graph changes over the off season to the 721. I want to add a second graph at the bow for Livescope. Looking for opinions on what guys have learned from different setups. How do the dual mounts affect factory covers? The biggest thing is I fish rough water like Erie and St Clair a ton. I worry about them being able to hold up long term. Here are the two that originally caught my eye. The Dek it looks like it might be a little more stable for rough water but that is just a guess.

I noticed the BBT mount makes you pick the graphs when ordering. That is concerning to me as I don't know that I want to be married to the configuration without trying as far as top graph and lower. Also don't know that I want to buy a new mount every time I buy a new graph.
