Hi guys...thought I'd chime in..

I too am saving for a set of tabs though I'm going with the electrics. I posted earlier about those Smart Tabs but after some further research, decided against them. Why pay $300 for something I can't adjust or control?

As for the fin...BE CAREFUL! I lost part of my cavitation plate from the 2 piece version. It was bolted on (2 bolts per side) and damned if the plate didn't break were the bolts went through. Mechanic said the combination of a heavy boat and the power of a 350 caused too much strain and off it went.
If you get the tabs, you'll have no need for the fin.
