Chainsaw Repair

Need alittle advice from you guys.   I own a 60 acre farm and cut wood for my heating.  Thinking on trying a 24" b/c on a small mount husky saw for limbing only.  I have both, a 346 NE, and a very strong 262xp.   Trying to avoid bending over so much when I limb.  Had back surgery awhile back, but doing OK till I bend over all day.  My 350 acted up on me the other day and wouldn't start while limbing, and so I used my heaver  61/272 blend w/24" bar to finish the job and was surprised that I had much less back pain at the end of the day.  I usually use a 346 or 1 of my 350's with 18" bars for this.  I know there are some small mount 24" bars out there, but my question is, should I go with a 3/8" with skip chain, or maybe a narrow kerf, or maybe a 3/8" picco b/c ?   Cost is no concern when it comes to my back and the Tsumira, SugiHara, and Cannon Mini's are not out of the question.  Balance & chain speed will take a back seat I know, but I am willing to compromise.  Any experience, advice or recommendations?  Thanks in advance 

Never considered those. How would those work when there a lot of limbs in the way?   I could see with bucking, but how bout limbing?

I know you said money was no object to worry about. But here are some deals by a member here  Left Coast Supplies.

Thanks guys.  I'm considering all options.  Now, if I could just find somebody locally with a bow saw.

Oregon offers a 24" in the small mount but only in the Power Match with a 3/8" tip, you would need to switch to a .325 nose which isn't a biggie.
