Quick,
I have an 080, and I ran a Tak 175 for three months. I like the Tak for balance, but the 080 runs the head better- One word of caution- WEIGHT
I have not had a chance to run the DC yet, but I would not want to be more than #1000 on the boom. I do not like my rockhound, but the weight of the 30 is great. The 40 is too heavy, and causes the machine to tip and puts too much weight on the tracks behind the boom (Where ever that may be...)
The Loftness weighs in at #1600 and is too heavy for this machine.
Just a word of caution... I am thinking of seling my 080 to get a JD120 or 160
