Jake,
I LOVE flaming invasives (especially with the ground as wet as it is)..
It is very cathartic. Feels like watching the wicked witch melt. Of
course the advantage is that perennials and most grasses recover fairly
quickly and no herbicides used.
Rather than buy the pre assembled kit, I bought the the torch and an
Alice Pack frame separately. A 20 lb cylinder feels good (attach to
frame with gripper load straps) so no need to buy the 10 lb cylinder.
Saved about $90.
Freaks out one of my neighbors, but he annoys me anyway. FWIW, I do
wear Nomex.
Regards,
Dewey Clark,
