Mantus has drug twice / Removable semi-permanent mooring?

[SKMT]

I've been on an 85lb mantus for about 2000 consecutive days. For the first 4 years it never once drug. Then twice in the same month it drug when a florida pop up storm ripped thru from the west (opposite of prevailing wind). Fortunately both times I was on the boat. Both times it drug at least 100-200 yards before I threw the back up (35lb HT danforth), which stopped the boat instantly. Both times the mantus came up without anything stuck to it or any chain wrapped (altho possible it unwrapped when raising with windlass from flybridge). 99.9% sucess rate is great for many things, but I need to keep my boat off the rocks 100% of the time.

I have a 44ft / 30,000lb trawler. What would be the best anchor for a triple anchor mooring? I most definitely would trust 3 Mantus', but is there any reason to shell out that much money for this application? I know danforths suck for a primary, but they are supposed to be top notch holding as long as they dont have to reset. If danforth is the anchor of choice, should I go with a Standard or Hi Tensile? Otherwise let me know any better option....
