I'm kinda wishing (now that I have my 60" single end bar) that I had a double ender to be able to use a nose tensioner. I guess I'll see soon enough how aggravating a 60" bar can be. My 42" is no big deal.
Humm, . . . chain tension is not that big a deal for me.
Time and weather still way too hot is the biggest deal for me right now. Today it was 106F (for you guys that would be like having a 106F day in the middle of September)
Probably the most restrictive deal for me is not having access to a loader to handle big slabs in certain situations. Meanwhile these logs continue to rot!
Double ender sounds like the way to go though. I might just make my own ?
