I've got a 27x5.75 70s fibreglass deck, not a polarizer, but Blender has ridden the same deck. Don't have Suregrips, use ACS 430s, which are equivalent sized roller skate trucks, and I find that 70s Tracker mid trucks are a better fit with 55mm, 78a OJ mini Juice. Less tippy feeling, and gives a nicer carve on banks. The trucks on the smaller 24" Penny boards are a similar size.
The roller skate trucks were never designed for skateboards, and only ridden by young, short kids. Bennetts were the first trucks designed for skateboards and were a bit wider to give a bit more stability. Don't have a set.
