backstay adjuster very desirable
Unless you have already committed yourself to your local outfit, I think you should check out the stay and shroud kit available from Catalina Direct. I used them myself and I am very pleased, not to mention the price, which includes new turnbuckles, is quite resonable.For your forestay, I think you should definitely put in a toggle at the top and have a threaded stud at the bottom. This will allow you to easily install a jib furler later.For the backstay, I think you should definitely use the backstay adjuster kit from Catalina Direct. I put one in myself and it makes a world of difference.Further, depending on the age of your C-22, it is very wise to install the bow chain plate reinforcement kit from Catalina Direct. This uses some hardware to connect the bottom of the bow chain plate (on the inside) with a turnbuckle to the bow ring. Nearly all C-22's have no plywood support where the bow chain plate is located and you can literally rip the bow apart with forestay tension.Finally, unless you have one, invest in a Loos Tension Gauge.
