I use the Zip Course tape (2nd set). It has about 2000 miles on it, about 150 miles in the rain. No gloves. My tape is worn at about the same spot as yours, right side more than the left. I have the replacement in the basement, just lazy about taping right now.
I have a friend that has leather tape he says it been on his bike for about 12 years. It looks really nice, like a perfectly broken in baseball glove. It doesnt feel comfy to me cause I like the cushy stuff.
