just replace the aluminum thwart with an Ash yolk from great outdoors Provision and get either clamp on or drill through shoulder heel cups like we used on big blue in the 90 miler. You are taking on about a 1b and half but it is worth it. I Carried big blue on all the up hills and most of the flats and had no problems. I personally prefer the clamp on type since you can adjust as needed...
