Thanks for the info! I like the ends on them most of all.

Great info here.

What's the average distance you guys trailer to ramp?

I'd say my distance to the ramp I use on most weekends is about 15-18 miles or so. We travel quite a bit with the boat with some trips as far as 10-12 hours during the season. To me, it does not matter if your ramp is 5 miles away or 50, the chance of having an accident is the same so I always strap before I go.

About 500 feet.
