I had my first few runs on a Venom 38 attached to a Isonic 111 & RSS 7.8. The first thing I noticed is the lack of any hint of spin out, something I need to watch with the stock Drake fins.
The fin had plenty of drive and felt very secure even when pushing hard in lulls. The water was smoothish and I tried a new mast track position on the board, managed to get a PB on this set up. I'm not sure what the main contributor was but the fin definitely delivered confidence.

May be worth mentioning that (first use) the fin didn't sit flush on one side of the box, so it had a little less rake than it should, not sure how much of an impact this would make.
Comparing to my other good fin, a Tectonics Falcon, the Falcon feels a bit finer and also provides a bit more feel in what the fin is doing (I think). But this is comparing to a smaller Falcon and initial impression if the Venom (need more TOW). I suspect that I'll be getting another Venom in a 42 to replace the stock Drake 44.
