Rock fish Rigging and set up Ideas?

I like the dropper loop when targeting rockfish and I'm trying to load up on fillets.  But when targeting big fish they are just too unreliable.  But Ive been using 30lb mono and a twisted dropper loop with about 5 wraps. 

I want to say that I wrap  mine only 4 times, but it might be five.  For me the trick is to use something to hook the "loop" too while pulling on the main and tag end of the line to cinch down the knot (after moistening).  If I dont hook the loop on something, some how the line crosses or something and when I pull it tight the knot it breaks and I have to start over again. 

OK UPDATE....LOL I was fishing with a buddy and he said 3-4 wraps with 40lb is not enough so I have tested this and sure enough I did a 10 wrap set up and low and behold its a strong as a heck the line broke but not at the knot just broke between the two loop knots. So I am going with this and hope next time I don't loose any big fish. How many wraps do you guys do for the Dropper Loop? Think this is correct?

I only do 3 wraps and I've never had my knot break at the dropper loop.  I use either 30 or 40lb mono.  I feel like the more wraps I do, the higher my chances of the wraps overlapping and I hate retying...lol.
