There might be variation in the gear that comes with the Integral. I just weighed a set that came with one one of my Integrals, and it came out at 4.45 oz, so the Bolly gear saves me 0.25 oz. The 4.45 oz weight is from a digital scale, and it's only the gear, no wheel pants, wheel axles, or screws.

One of the things I like about the Bolly gear is that the wheel pants have features that fit around the gear legs so they are automatically aligned when you screw them on.

For those that are using glow power I believe that there are Bolly landing gear choices that are even lighter if you don't need the clearance for your prop.

If you're nose heavy you might want to consider a Carbon Fibre Spinner. I'm using the one from Netbox hobby, (they only have one size ...) and it fits perfectly. In actual fact, it's the only one I could find that did fit.
