I am like elknut1 as well and I do the no mess way of quartering an elk. The only difference is that I only use a saw to detach the head. The rest of the quartering can be done with a knife. Why waist the time gutting an animal if you are going to quarter it out.
As far as packs go I do not own a pack frame any more. The Jim Horn signature series packs from Blacks Creek Guide Gear is the best pack on the market in my mind. It is a day pack that you can pack meat with as well. I will never use a pack frame again. This past year we packed out 5 elk using two of those packs. We tested the limit of weight and had no problems. Go to www.Blacks-Creek.com if you want to check them out. I used the Western but I have upgraded to the Alaskan.
Good luck,
