I have had both on a 26 foot 5,000 lb boat....bunks R great once U adjust them...no guide ons.... drive boat on down the center....may have to crank a foot or so....I find that most boaters do not adjust the bunk guides.
Take a rainy day, do not have to worry about boaters... go to ramp have your wrenches to adjust, most of time only have to adjust the rear of the bunks...may have to test in the water a couple of times...
