Hardline DVS or The One is what I usually recommend. The DVS is the Detachable Handle System that allows for changing the grips easily. You can wear the handle out and not have to buy another one. The One is a carbon handle. As for line, the T-Cor is great. It does not tangle easily and floats.
Other options include the Fly High handles. They are hard rubber extrusions. The are the most durable on the market, but not soft. You can also get Tak-Line. It is limited stretch - about 2" at full length, so it is much easier on your shoulders when landing blind. Spectra has about 1/2" of stretch. For us older guys, every bit helps.
