Konrad is the way to go, but there is nothing "wrong" with TRS's. The Konrads are big $$$$, especially when you consider the value of the boat they will be going on. I worry more about my bravos with 454's, than I did with 600hp through a TRS. There may be some speed gains, but on a big heavy 38' strait bottom, you won't be setting any speed records anyway.
