Go for the 00089 and fit resistor caps, but do not use resistor plugs at the same time, you will get the system cheaper by going direct to boyer, they are easy to fit and work really well, technical support is first class, i used to live 10 minutes away from them and always went to the production shop, they are a small family run cottage type business working in the grounds of the family home, just 4 people1 baby and a dog the last time i went there a couple of years ago
