Another vote for the truss/strut scope.
I have the 12"Lb, and being able to break it down into smaller pieces makes all the difference when packing the gear into the car.
I've seen people trying to manhandle a solid (12") tube, it looks painful!!
The only collimation I have to carry out is a couple of tweaks of the primary knobs, a minute at the most.
And on a couple of occasions, I've put the scope together, slotted in the Chesire only to find that the scope was still spot on!!
So don't let the bogey of collimating a truss/strut put you off buying one of them.
Their only drawback to the solid tubes is the price. But it is a small price to pay for portability.
