Funny you should say that -
In Bishland the most question often asked by newbs is "Whats the fastest plane".
Only one answer and off he goes in his Lala, may account for the Lala being the most used of any plane.
But proves one thing, in the MA speed is everything.
At typical MA furball alts the 16s speed is approx 380mph, hardly stunning compared to others.
Its max speed is at 20k and its still less than 400mph, hardly a bit threat to Ponys etc.
OTD its only 354mph still way behind what could be considered the big 4 or 5.
It won't turn as well as a 9 because of its clipped wings, all it will really have is a great climb rate. Good for intercepting IB bogies, unless they decide to run.
How many 262, Temps etc are killed by slower planes diving in from higher alt, Spit 16 would be no different.
Thats why I dont think a 25lbs Spit 16 would be that much of problem, there's just too many planes can catch it at all alts. You can also bet it not only being chased by say the invetible Lala, you can almost guarentee there will be slower better turning planes there also.
Whats worse the single Lala chasing you, knowing you can prob get to the Lala to run away. Or the Lala with say a couple of Spit V's tagging along behind just waiting for him to turn you?
The MA is so chaotic in a furball I doubt a Spit 16 at full boost is going to be anymore of a problem that your average late war ride.
Actaully a good example is the Spit 14, bet you've seen a lot more now the perk cost is down, I know I have. I have also seen a lot shot down, yet this is the uber Griffon engined monster.
The only problem I see is misunderstanding. People will assume as it's a 16 it must be better that a 14 not realising it really just a 1944 Mk 9. Yes probably see a lot of use initially, but most will go back to their usual Lala, Pony rides etc. It would prob become the Spit ride of choice for low alt furballs, but the 9 would be used for higher alt stuff, and for range the 8 would be used. Whatever happens once the 5 is de-rated it will rapidly becamoe a hanger queen.
My own personal choice at the moment is the Tiffy, only because it stands a chance of catching the late war stuff. My ride of choice would be the 16 @ 25lbs, slower that the Tiff, 2 less 20mms, but its a Spit. Wont even bother trying a Spit 16 at 18lbs.
Just my thoughts.
