Bike lock choice and security strategy

Ciao folks
Those who read my first and only thread, Accidental hybrid purchase - test ride, will be aware that a few days ago I became the proud owner of a Boardman Comp Hybrid. My first brand new bike since my Chopper in the early '70s

As my previous hybrid cost me £30 I only ever used a cheap plastic coated Wilko coil lock and suspect it never got nicked because it was worthless. Now that I have a bike that might be attractive to a prospective bike thief I need to consider increased security.
Having done some research earlier today into security requirements, equipment and strategies based around the great information on The Best Bike Lock website, for my my circumstances where the longest period it will be parked anywhere other than my home will be probably 15 minutes outside the nearest Aldi, I've concluded that a combination of the On-Guard Brute STD-8001 and a looped cable/cable lock for the wheels would be more than adequate.
I'd really appreciate your views of my choice and any alternative recommendations.
I've actually ordered it for delivery tomorrow but can send it back for free, if necessary, as I'm a Prime member .

Two of my bikes were stolen, the first one was locked with regular cable and second one with steel lock. I have no idea what tool was used, but i found only part of my lock at the place where my bike was supposed to be.
Your choice looks reasonable, strong enough and not too heavy. Also you can take the seat when you leave your bike. It will not stop thieves, but you will save the seat (i still have it from my first bike).
