I am looking to purchase a Woodland Mills Woodchipper for my LX2610SU. I will be using it to maintain my 70-acre New Hampshire woodlot which is on a hillside. It contains primarily hardwood, with some mixed hemlock and white pine. I was initially looking at the WC68, but I see they now make the all new TF68 Pro (twin flywheel). In addition to the twin flywheel, it looks to have gas-charged springs, and a chainsaw holder. The only negative I see is that it weighs 50 lbs heavier. What few reviews I can find are positive, but I am unsure if it is worth an extra $900. Have any of you had experience with the TF68 Pro? Or for those of you who already own a WC68, would you consider jumping up to the TR68 Pro if you had a chance to? Would love to hear your thoughts on the TF68 pro.
