He didnt read the instructions
.....I have installed a CDI unit on both of my previous boats, a Cat 22 and a Columbia 26 MKII and have helped friends with a couple of other units and I have to say I would recommend it for anyone but hard core racers. I think the plastic luff is a little heavier then an aluminum foil on the others like the Harken.Pros: Plastic luff is less likely to get tweeked when you take your rig down. Internal halyard eliminates halyard wrap and leaves your old jib halyard as a spare. Simple design is maintenence free and easy to fix. Great reefing abilities. Great furling abilities. warentee even covers "unseaman like behavior". You can but a CDI unit and still have enough $$ left for a sail compared to the cost of a Harken or Schaeffer system. Owner installable.Cons: Heavier. Single groove in foil prevents you from striking one headsail while bending on another (who does that anyway?) Internal jib halyard does not lend itself to tightening the luff of the jib to adjust the draft. (Again, who does that?) Doesnt come with a Harken sticker.If you get the CDI get the ball bearing upgrade and spring for a new head sail with a foam luff pad to improve the shape of your reefed sail. I'm not sure about your local conditions but you might want to go with a larger head sail. Remember, you can always reef a 130% down to working jib size and still maintain good shape. Have your current headsail recut into a "blade" for heavy wind days.As far as the reviews, the first guy didnt read the directions. The luff is easy to straighten. Just follow the directions. What is really funny is that the directions specifically say not to do what that guy was doing. Its the only thing the warantee will not cover. And the second guy just doesnt make any sense.From the manual on the website:"Uncoiling the Luff Straightening the LuffPART 2: STRAIGHTENING THE LUFF· Holding the luff flat on the ground with weights and/or using ahair dryer DON’T work and void the warranty. Follow instructionsbelow."Too funny.
