I’ve got a 2019 process 153 29 al which up until black Friday was “my best bike ever”. I had the old kona 134 previous to that and kona pretty much rectified the only fault of that model in that it climbed like a sack of spuds, whilst still keeping all the good things and downhill ability. Alas tho intense UK did some crazy deals on their carbine model on black Friday (£1730 foundation build) then upgraded me to the SL frame free of charge .In my opinion the carbine is a better all round bike but definitely has a different character in so much it wants to go fast all the time uphill as well as down ,whereas the process just is just a bit better for pissing around on but slower everywhere according to strava and sounds like i do a similar sort of riding to the OP .finally weight difference between the two was nearly 3lbs with the same build kit
31.4 vs 34.2 .if your a medium cookci I could do you a sweet deal ;)
