Got a Transition Preston that I currently run a DHX5 on and love it except for the weight. Working at a shop I had the opportunity recently to demo an RP23 (no boost valve). The RP made the bike great on jumps due to the less weight compared to the DHX. However on the trail when it came to roots and rocks it felt jarring. The rebound also felt like it was always too slow. I spent most of trail adjusting the shock trying different things but was never happy with small bump compliance. So was looking at the Monarch 4.2 which seems lately that is pinned against the RP in tests. I am a lighter rider 160 lbs. I would most likely only use this on local trails and use the DHX on park and gravity feed days. I am a do all kind of guy hit the drops, jumps, and still climb if I need to. Would like to hear what experiences people have had or are having with the 4.2 as well as what setup you are running on it.
