See, that's the difference for me. I don't do well with Asyms (except for a Sure Lock which is working great right now) and since I will be all year as a house bowler at these two fine establishments, the HCF just doesn't fit the bag. I got an Idol, admittedly used off Ebay, to be a replacement for my Phase II, which is getting old and is a high maintenance cover, but the Idol, although interesting, is less overall than I thought it would be. Although I don't usually like Asyms, I need to put this drill on another asym and see if I've found something or if it's just that the SL is that good....
