text has always been my backbreaker too bro.....dont sweat it too much...its a pretty common problem. i usually cycle through about 50 different ones until i feel like i find one that fits the sig...its pretty much what i dislike most about making sigs outside of cutting out players.
as for your sig..i would tone those scan lines way down.....especially for a sig at cafe limits...they kill the quality on a sig at 12KBs. id probably tone down the color on the BG a bit too to bring the pic of bush out more.
nice lookin sig tho....comin along
