Wiredsports has been super cool on this site, so I'm saying what I'm about to say with the utmost of respect...
Those boards/packages are cheap for a reason. They're "off" brands
An excellent beginner all the way to pro board is the Capita Horrorscope which is really soft, or the Capita Indoor Survival which is a little bit stiffer, but still really soft. They're good boards because of the FK technology which is a style of reverse camber that elevates your contact points so catching an edge is more difficult to do. Reverse camber also pre shapes your board into the shape that it takes when carving, making it easier to carve.
I believe there's a Capita Sierrascope on here for sale right now that would work for you...
I'm 6'5"ish and 175-200lbs and I ride a 155w Horrorscope all over, until things get really choppy. Then I bust out my 162w Capita Black Death.
The Sierrascope was a big shorter I believe, but with your weight it would be perfect.... Use the search feature and buy the dam thing ( =
