Only went for thule for the simple reason of being able to add the ladder tilt at a later date, plus it's hard to come by a decent roof rack that fits the connect. I've always gone for budget roof racks in the past, but this one is aluminium, nice and light weight, no wind noise, and as said means I can fit the ladder tilt. Didn't fancy ladder rollers as I like to keep the ladders clamped with winder clamps that I can padlock over night - assuming you were thinking addind rollers with stalks that dont secure the ladder.
Ladder tilt looks great as means you don't need to use step ladders to clamp
