All that and I'm much improved from last year, so it's time for the next step up. I think the 3 port might be holding me back slightly. I'll find out though. The 21BF is getting refreshed for a backup, so the 5 port can be the big race engine. If the Plus21 is too much I can always let off the trigger. LOL.
