Are you planning to test them both as one as your picture, or separately as most of us will be without the extra flare.
I would be interested in seeing the results of one labhorn., and also both stood side by side.
Then it would also be cool to see what difference that extension makes to it.
That would be three separate tests, but it looks like there are alot of us really interested in your modifications, and would like to see your results and if you will (when you get time as we know your spending every second you can to finish them)post your plans so we can make your design as I suspect it will be smoother and go lower.
