Sounds good but my dillema is for 80 bucks more is the s5 that much better than the nova and for the same is it better than the go?
No, but RB is the name, the S5 is going to be smoother yes=shorter stroke, the n21 has alot of bottom but is very drivable indeed, yes the GO 5 IMO is stronger and faster overall than both, but can be harder to drive with that in mind, the Limited n21 is a shorter stroke than the BF standard, so look at that as well, if you like the RB S5, i have a PTM S5 L2G NIB, but it's over the price range. I really thing you will like the NR, unless your track has 200 foot strait's then your in trouble.
