I have read older posts from time to time and I keep seeing people state that slalom wakes are great with the wake plate down. I have an 04 Outback without a plate. I like the wakes fine. I am always interested in making the wakes better; therefore, I wanted to make sure that Im reading correctly.... The plate is down, as in pointing down towards the bottom of the lake. Hopefully, some one can verify. Also, any ideas on how expensive it would be to have the plate installed aftermarket? Thanks in advance for your help.
