Indestructible Tab

This is what I`ve figured out for this song but it doesn`t sound completely 
right, I`m hoping someone can play with this tab and come up with a better 
version because this is a deadly tune.

e------------------|
b---------------15-|
g--------12--------| x4
d--12h13----13-----|
a------------------|
d------------------|

the 5th time it ends like this:
[ Tab from: http://www.guitartabs.cc/tabs/m/matthew_good_band/indestructible_tab.html ]
e-------------------------|
b-------------------------|
g--------12-----x-8-------|
d--12h13----13--x-8-x-8---|
a---------------x-6-x-8---|
d-------------------x-6---|

It then goes into something like this little riff:

e--------------------------------|
b---------------------4-----4*---|
g-----------------*3h5---3h5-----|
d--------------------------------|
a--6~-6/8~-6/8-5-----------------|
d--------------------------------|
*Only played the first time.

That sounds pretty good to me, but let me know what you think. I can't seem 
to get the rest of the chords but hopefully this gets you started.
