Wow! 90 hours is incredible! Hopefully calluses will still develop even though I'm using gloves. I do eat well and work out too so I'm hoping to get stronger for next year. I actually have been using Mechanix $25 gloves with anti vibration padding in them. Although I'm not sure if it's gel in mine, they, along with using an Echo vs a home owner brand trimmer, have eliminatied the numbness in my fingers! THanks for the info Lugnut!
