I use a Prophet with AM wheels, a longer stroke shock and offset bushes to get it to play nice and slack with 160mm coil forks, I can also use lighter 130/140mm air forks with the original shock and spacers with a lighter set of wheels and tyres as an all day bike as the manufacturers intended.
AM setup 34lb
XC setup around 30lb
2 bikes from 1 build but due to it being a trail frame and me being 18st I have to be shy away from the bigger DH jumps/drops. It would be fine landing properly but it wouldnt take me landing badly too often but thats what a DH bike is for.
Have to admit I also have a HT for proper epic day rideshich is where the shorter forks and lighter wheels normally live.
As mentioned above, if you can carry the weight/downhill is the fun bit for you then a 6″ bike like the Mega/Alpine 160 would be the way to go. If you enjoy climbing as much as descending and longer days in the saddle I’d go for a slightly lighter 5 style bike.
