Chainsaw Repair

I'm trading for a used JD 800 at the moment.  So I got a question for you guys that have run these Echo 8000 and John Deere 800V.

Will they pull a 24" or 32" bar bar in rip cuts quartering dried hardwood elm etc?

I have sold all my 122cc 084 and 118cc 3120 and 166 and sold one 066 so far. I have 1 066 woods ported for doing the duties now with 24" and 32" and haven't had to use it yet this year.  I'm thinking of selling it if the 800 can do the duties. What do you guys think?
