Much like Tom, I always have my Silky Zubat attached to my shin. On larger scale jobs, I also carry a Stihl MS200 with a 14" bar. On really large take-downs, I sometimes rig-in and use a MS460 Magnum, but this isn't the easiest on the lower back!
everyone on my crew climbs with husky 346xp 's and silky ... we stoped using the one handers a long time ago .... imo a over the top handle one handed saw is a good way to get cut ... my guys are addicted to the 346 xp power now anyway dark
silky is nice but .........4 speed .......use a big hand saw 16 inch at least with the cutting on the pulling action ... we can pull more than we can push IMO
