Have you looked into the Vruk pedal attachment? I'm not currently learning a heel toe technique for bass drum but in the future I'm going to want to try and learn due to a 121/2 EEE foot I may have some issues. I researched and this Vruk looks very interesting. Check it out yourself at http://www.vrukpedal.com
it seems to not only improve the way the beater strikes but it also extends the length of the bass pedal. I saw one of these sell on eBay last week for about $80.
