How does the weight compare, between say a quality SM 17" spokey rim and a decent forged wheel?

Re: Bikes with spoked wheels
 

I have had more punctures with tubed spoked wheels. (BMW tubeless spoked are cool and work).

Go down FAST! too.

A KTM Adventure is nearly my perfect bike, but a 100mph blow-out? Nah, no thanks.:( (Wonder if the new one will have a mag option?)

On the road , tubeless therefore mag are defo less pain. At the mo I have a nail in the tread part of my rear tyre on the SV. Done 1000miles. No loss of pressure. (A waiting game!?[-o<:p )

Necessary for trailies. Look cool on SM's.

In addition to the above tubeless have a number of advantages, such as more consistent temperature so wear rates and grip are improved. When punctured, tube tyres go down FAST, (and if that's ever happened to you you'll be pleased to reduce the chances of it occurring again), valve tearing isn't a problem, neither is tube chafing.
Tubeless tyres may be slightly fussier to fit, (but if you've ever pinched a tube when fitting you'll possibly reconsider that), but have advantages I wouldn't forego.
If you do have tubes replace then when punctured, they're not dear and I wouldn't run the - admittedly small - risk of failure, (see the rapid deflation comment above), unless we're talking about an extremely lightweight bike.
