A Request for Bike Tube Manufactures: Put the Seams Away from the Center!

I've repaired my share of flats in my day and 9 times out of 10, the puncture is at the center of the tube. And, it's usually right next to the joining raised seam of the rubber tube. For repairing a flat, you have to ground down the area around the hole with that mini scraper. With the puncture next to the seam, it makes it harder to grind away most of the raised joining seam. Sometimes I've had unsuccessful flat repairs because I didn't prep (i.e. grind down the seam) the area around the hole enough.

I was wondering why bike tube manufacturers don't put this seam on the sides or at another place where punctures don't usually happen. Or, how about putting the seam on the inside of the tube (and inverted seam tube!)? I don't know if this is even possible with bike tubes but I thought I'd post about my gripe.
