We've had success in Annapolis with UK for many years and after adjusting to North's tuning guide have been happy with our speed. The UK Gold Tape Drive we bought in 2005 still looks good after 30 races. Note that the North 2007 Kevlar Medium #1 we use is not a 3DL, nor is the New Orleans Benz-Faget-mojo #1. The UK might be a tad heavier and the 3DL probably the lightest. Better Mousetrap is Quantum and always tough to beat. Ignoring that and price too, find a sailmaker that will help you setup your rig tune and then sail with you a couple times a season. It helps if you get along with them, since you and your crew will be spending your leisure time with that person. I've worked with Alan Drew (UK & North) for a long time and have been helped by Scott Allan (UK) and Jonathan Bartlett (North), but there are many more. Take the time to find a person who will work with you to improve your program.
