Looks like RJ's have it hands down. I bought the Kuryakyn shields and they work and look fine. I am not familiar with RJ Originals, maybe they aren't available in Canada, If you expect heat shields to be the whole solution you will be disappointed. They help sure but acombination of things including true duals, aftermarket ECU tuners, dyno tuning, synthetic oil and even Nightrider XiED's all help. You are sitting directly over a very hot motor and when in traffic at 85 and 90 degrees, you will cook!
