When you remove the RkCrawler MD 55 from its package, there are absolutely zero modifications necessary. It comes standard with a set of Gamakatsu Round Bend Treble Hooks (I buy these hooks in bulk because I like them so much) and high-quality split rings. These hooks have always given me a very high landing percentage and they tend to stay sharp for an extended period of time. It’s also worth noting that I haven’t needed to tune one of these lures before fishing it. I’ve tinkered with ’em after bashing them against rocks for hours on end, but that’s about it.
