How does the carbon race wing goes? any significant ride difference? How does it go on straight line? really keen on getting one :)
It's taken 4 or 5 sessions to get the feel of the new faster foils and I can summarise as follows: like putting high end wheels/ bearings on your old skateboard

top speed im guessing is nearer 25knots than 18 with the learner foils. Points just as high as learner foils , just a lot quicker.
for learning toe side and tacks Im thinking I should stay on my starter foils but will probably stick to carbons now.
no issue with tracking - I am tuning the angle of attack on the rear foil arm - using different thickness nylon washers under rear bolt.
have kept old foils for resale or passing on to my lad if he wants to learn foiling.
i kept the straps in same position as I had for old foils....thinking front foot may need to be forward an inch but not sure yet.
hope this helps
