geez, I think I've had just about every kind of trailer there is over the years, and it really is more a factor of what you want to accomplish. For ease of launching/loading rollers are easiest if you are going to be winching. Bunks spread the load over greater surface area, so are great for long hauls where pounding down the road will eventually cause wear on the hull, but can be a pain to launch unless the boat is nearly floated on and off, which can be a pain in itself if the ramp is at a shallow grade, the water is rough, or salt exposure is an issue.

I have a trailer that is a combination of the two...rollers down the center and bunks on the sides. It's actually for a dual hull Livingston, but the concept is, IMO, the best of both worlds.

When you get it right, you'll know it. Spending too much time at the ramp launching or loading will make you the topic of many unkind conversations. Good Luck.
