Most comfy shorts?

[Trekhawk]

I'm riding the MS150 charity ride April 21-22. it's 100 miles the first day and 80 miles the second day. I'd like to invest in some really comfy cycling shorts for long distance cycling. Any recommendations?
Has anyone tried the LG Carbon Ion HFlexx shorts or the Shebeest SB Ultra D Shorts?

Thanks, michele

After contemplating the loads of shorts on offer I finally went with Assos (same price as the LG Carbon shorts). Im going to try them out tomorrow. I will let you know how they work out.
