I started with the NP AL pink foil on my 85 wide slalom board and it did the job, but when I changed to the full foil board (JP 135) it just made everything work better. I then changed my foils to the Starboard GT-R set up which is even better again, so my advice is to get the foil board when you get your foils if you can.
If you are a fan of slingshot gear, you can buy their foils with a large freeride style wing to start with, and buy a faster front wing later on because it's modular, so you just change or add things as you go. I hope you get the chance to get out and have a go soon coz it's awesome. :)
My excitement for this is definitely building! Looking forward to it!
