OP, I just scanned through a few posts here so bare with me. First, all engine builders had to port their first cylinder at some point and with the sport port templates just follow the lines as best ya can, as smooth as you can. You're not trying to come up with a new way to make power or try different timing. I'm with ya, just do it and stop the back and forth with people. For your tray, footholds and basically just the whole hull mods youre doing. You asked for some input and ya got it. You got other peoples opinions and ya don't like them, ok that's fine. I do believe most comments were meant to help save you some frustration and were not meant to be malicious, while others not so much. You're not going to convince anyone, ya don't need to. You've convinced yourself that these are the things that you want to do to your hull and you feel it will make the hull better for you. Just do it, you've gotten plenty of input, how much more of the same do you want. Off the keyboard and into the garage son. Get on it and make it happen. If all the work you have planned just messes your ski up, well you'll have a messed up ski, but will have walked away with more experience. Plenty of cylinders that didn't "work" in shops of reputable builders. Plenty of hulls met their buddies at the dump too. Good luck and have fun. P.S. fwiw I'm pretty interested in the Stryker foothold setup.
