So I guess this comes down to money spent to see a justifiable gain. The saying goes is the juice worth the squeeze. As mentioned if your not racing then a smaller mandrel system is fine. Good previous posts . Fitting a 3 “ system can be a war. I went to a bigger system ( make more power) but I’m racing a little and thought build bigger for the future . In your case that’s the only consideration u will need to decide .
