Hi Ben, welcome.
I have done a lot of anchor research. 10 Kg Rocna is good choice. Mine has never dragged (touch wood). What I have found out is the effect of chain is less than historically claimed “catenerary” only exists a low pulls. Once wind gets to 20kt even a full chain anchor rode becomes a straight rod. Strong but no lowering of pull angles. The most recent theory is go with bigger anchor rather than more chain. Chain becomes chafe protection so only need 20-30 feet. I seldom anchor in more than 30 feet of water. With 150’ total rode that would give scope 150/35(depth+freeboard)= about 4:1 ample for most secure anchorages but not sufficient for exposed conditions requiring 5:1 or even 7:1. My suggestion would be keep Rocna and 30’ chain but look to increase nylon rode.

Still thinking about replacing lifelines with dyneema.
