Thanks Rodger,

I have no plans to make this any harder than it is. I am looking for as easy as possible way. Since Kooks are known at they make resonable power i plan to make same lenght primarys. I am mostly intrested is there any gain to go with merge collectors? SPD has some nice ones with right flanges.
