11 hours per week, impressive! I have the Ringside bag gloves with gel and they work pretty well. When I'm really going at it, I use wraps and also put a small sponge on top of the knuckles first. However my trainer helps me put on the gloves -- don't know if I could drag them on with all that wrapping. Ringside also sells a foam knuckle protector which you could use.
As an orthopedist's dream, I would warn you about letting too much damage occur. When you're older, these type of injuries can cause arthritis or just limit your range of motion.
