The Letter Game 2: LONG words

Hey everyone!

This is the same as the original Letter Game, with the same rules and such, except that instead of trying to make the word as small as possible, you try to make it as large as possible! Therefore, you should first try to add a letter, then if you can't, change a letter, then finally, as a last resort, drop a letter. If you need reviewing on the original rules, see the link here.

Let's get started!

I'll begin with:         a 

has

hash

haste

waister

waiters

this word wuz used already

is this a legitimate word?

waisters

I'm going to change two letters to 

painters

                                                          .

paintier

Yeah. faintier? paindier? paintied? That second "i" really gets in the way. 

lol .. wuz only word i could think of 2 make previous word longer by only adding a letter but guess u could always change 2 letters again! might also b cool2make a letter game that allowed us2create a new word use'n the same letters as the word posted b4it > or use same letters +/- a letter, etc.

Ok, I'm stuck. We should start a new word.
