I took advantage of a Black Friday sale about 5 years ago from Speedmaster and got a set of those heads they have proven to be a hot little upgrade it was hard for me to move away from X head's after many years of great service and all the time that I put into them but I have no regrets in going to the Pro Comp head
Thank you for that post! That is exactly where I'm at now.. I have quite a bit of time and money into my 596 heads and curious to what my new results will be with the Speedmaster heads.. I know one thing they're going to be 50 pounds lighter!...
