FYI: my experience so far is predictor 10k has been the best. But a little heavy for a roof mount I think. And that's where I'm headed now. Probably wind up with a 3'-4', and swap out with this sirio 5k when I'm sitting and playing with dx/skip.
Again thank you all.
Just go with the Sirio on all the time. It is a stainless whip you can tie into a knot and it'll spring back. I once put one coiled up in a suitcase for 24hrs and it sprang back just fine. It has little wind resistance with the weight at the base so will be fine for permanent roof mounting.
