There really aren’t any aspheric throwers that can throw farther than the K1. The only one I know of is the Microfire H20. The LEP flashlights use aspheric lens but the tint shift is so bad and the CRI is so poor that you can’t really make out what it illuminates. I own the W30vn CW, W30vn HICRI and W10G2vn CW and while they are fun to play with, they are really more toy than tool.
Texas Ace is testing an aspheric mod with the BLF GT. That would make for a very useful no-spill light.
