I use a Sonik Vader S&M Hybrid Spod and Marker.
Biggest problem is the 50mm butt ring, they do get chipped easily in transit, I have had to replace it twice.
Personally I prefer 40mm butt rings and the 50mm does NOT improve casting distance. I can cast Century Big Bertha with 40mm butt ring further, but as I use the one rod for spodding and marker/leading around now I slimmed the tackle down.
