14 are moderatley high lift for hydros and deep V's
X4 are medium lift general purpose props
M4 are like X4 but with the tongues removed to unload the prop
I guess a moderatley high lift prop on a deep v can help hold the bow down? Got that from the Octura prop description list.
Different types of Octura props
12 are low lift ideal for submerged drive
X4 are medium lift general purpose props
M4 are like X4 but with the tongues removed to unload the prop
Y are like X series but have 10% more pitch
X5 are general all purpose med lift prop
X6 are higher lift than X4 and suitable for surface/semi surface use
14 are moderatley high lift for hydros and deep V's
16 are high lift props for riggers and hydro's
17 are the highest lift prop for riggers and outboards
P7 are similar to 17 series but more rake and less lifti
19 are high lift for riggers and hydro's
V9 are moderate lift suitable for riggers, hydros and SAW racing
20 are moderatley high lift suitable for riggers
21 are high lift for riggers and hydro's 22 are high lift surface drive only good straight line speed
The tongue is used mostly when taking off and low speed acceleration. Removing the tongue allows the prop to turn easier at high end rpm for a faster top speed.

SO the tongue is epual to putting small tires on a car you take off quick but not for long. So from what I got from that is if you mess with the tongue you can get a perfect prop. You can shave a little off and get the right amount of acceleration to fly at the start. Plus you have a small enough tongue that you get a good top end. right
