I'm by no means an expert but I think it's a good idea because you'll then have the flexibility to do 4s, 5s and 6s and be able to play around with different gear set ups as well. I geared 26/58 for speed runs and gps'd 61.2mph on 6s. Then geared 22/65 for grass/dirt yesterday also on 6s. I had trouble keeping my temps below 160f on 4s (this with smooth can), but the teckno neu is finned so you might be ok even on 4s. I'm up loading a clip from yesterday and will post here as soon as it's done.
here's the vid. Might want to turn sound off. Audio got corrupted when I joined clips.
