Last night, I weighed myself (92Kg) and then held the front wheel of my Pylon8, to shockingly discover the weight of the complete wheel to be...
3Kg! 
The breakdown of components on the wheel that I can name are:-
EX-S rims
36 spokes
Shimano HR-BM65 hub
Shimano BR-485 brake 160mm rotor
q/r skewer
Innertube
26"x1.75" Schwalbe Marathon Plus
Rainbow Racer
Reflector
15 spoke beads
Speedo magnet
Now I'm aware that my tyre is ~980g, but thats hell of a lot of weight when you think its possible to get 2Kg wheel sets!
Any (constructive) thoughts?

Wow that is heavy, a typical front wheel is under 1Kg (all 3 of mine and the daughters all are), your heavy tyre is 1Kg, add circa 125g for disc and 200g for tube and your still over by circa 700g.....
Why not remove the tyre and tube ane weigh each seperately (the wife lets me borrow the kitchen digital scales!)

WTB slickasaurus, 26x1.5 550g.....
Most Hybrids have puncture resistance which is heavy, but by my above calc your still 700g heavy!

i remember thinking my old wheelset was a good one and light, untill i weighed it and found the front to be 1200g! haha! rear was 1800!
new wheelsety at 2kg = 1kg/2lbs saved straight away!
sadly i have no idea if hybrids use mtb or road wheels! but pretty sure you could save a considerable weight with some replacement wheels!

The Pylon8 takes 26" mtb wheels, upto at least 2.5" wide.
If I was to order a custom front wheel from Merlin, what would you guys recommend?
I'm tempted to use a Hope Pro 11 q/r disc hub, providing it can use my existing brake rotor that is secured by a lock ring.
Given my ~95Kg weight and the fact I like doing a little off-road (bridle paths; woodland trails... along with road), what rim and spokes would you recommend?

i dont think hope do a centre lock hub, but then you can get a disc for a tenner through 'bikefridge' on ebay!!

At the end of work today, this idea may have been put into touch...
New job does not have secure bike cage, been told personal bikes have been damaged/pinched from the open stands (with rain cover). Managers have let me put my Pylon8 in the training room indoors today, but I may need to start using the vunerable outdoors later this week. Given it is ~£800 bike (plus upgrades) to replace, I appear to have several options:-
Insure Pylon8 and get a gold standard lock eg. Abus Granite-X
Buy a cheapy bike to use for work
Use the company's Halfords cycle2work scheme to get something new!! 
Now the only issue with c2w is a dilemma:-
Do I buy the cheapy new commuter through this
Buy a nice spec Fury/ Boardman Hybrid through this, not use it for work (naughty, I know) and then privately buy a cheapy commuter aswell 
Like nicklouse suggests, I could be horribly wrong with my wheel weight anyway and its not as if I am anything like a "weightweeny" , given the spare tyre around my waist!

buy a cheap old rat bike for work, no lock will stop thieves who actually want your bike.

Spoke beads are a new addition, to vocalise my bike sutly at slow speeds, while using an underpass or in the warehouse.
Colin, anyone who knows me in person knows I enjoy my food, I hate food going to waste after buffet parties for example. I get major carbohydrate cravings in the winter months, one of the more mild side effects of my S.A.D., which I hope my postie job will help keep under control from a calorie perspective

Halo bolt through skewers - 31g front.....
Never had a 26" 300g tube though - about 200g surely, although my mates 36er had tubes weighing 500g ea, now on 250g 29er tubes.
