Here's a few,
1. DR Lo-Riders 50-70-90-110's
2. D'Addario Xl Nickel Rounds 55-75-90-110's
3. GHS Boomers Nickel Rounds 50-70-95-115's
If you're playing in standard tuning, I don't advise going higher
than a 115 for an E string. Both the D'Addario and GHS' are the two most common heavy guage you can find.
If you can't find them at a store go to
www.juststrings.com
Hope this helps.
