Buying non-shit caster is by far the most important part of making creepers. Buy the good ones, cause they are gonna be abused.
Not 100% sure who made the ones at our dropzone, a local jumper I'm sure, but they are really nice. 4 amazing casters, padded and covered with vinyl with plastic edging to prevent any damage to the vinyl. Comfortable and roll really nicely.
Again, it's all about good casters and a durable surface material.
