I had this same dilemma early last year. I couldn’t make my mind up between the Nomad or a Blur LTc. I went for a HD instead so that I had the option of building two different styles of bike setting it at either 140 or 160. I have it set at 140 with a 150 fork, it’s my main bike so 160 for my general riding would be a bit OTT.
A lot will depend on how you expect your suspension to work and what bike you’ve been used to riding previously. I came from using an Intense Tracer (VPP) which used its travel more readily than the DW link HD. To be honest I wasn’t sure if I liked the change but now I wouldn’t go back. It isn’t as smooth on the smaller stuff but it soon opens up on rougher, rockier terrain. I prefer this as with it being my main bike it doesn’t feel like I’m too over biked when at a trail centre or such like. With me living in the Lakes though it works out well for when I’m riding rougher, natural trails.
Have you looked on the Ibis forum over on MTBR? I think a lot of the Yanks are using Rockshox Lyriks on their HD’s. I don’t know how far you are from Cumbria but Whinlatter Bikes in Keswick have the HD’s on demo. Biketreks in Ambleside should be able to sort a demo on a Nomad too.
