....my Dago Red has on OS .90 FS in it (4-stroke)....
with a 12-9 Zinger....although not really fast, it's a
good combo....next one will have the YS .91 FZ.
The .40 size F-20 has a Rossi .45 long pipe in it. it's a
screamer.
The .60 size F-20 (both Cermark) has a Tower .75 in it.
The next on will have the Rossi .91....
