i climb slow and quiet...and also try not to overheat. but i still get to 15-20 foot in a couple minutes. 2-3 minutes probably depending on tree. cherrys with the loose bark is really tough to be quiet on so i really take my time when hunting trees like that..
like Josh, i also climb in big intervals..a good couple feet at a time. i will pull my top part pretty high and then pull up the bottom half with my legs...if i sit and climb, it takes longer and is slow goin..a foot at a time..i still sit...but first i kinda hang pull it up, stand and sit down..pull it up as far as it will possibly go and start over...dont know why i do it like that
