1199S, all the power you'll need, look great, loads of used bits of bling available and come standard with some of the lightest wheels fitted to a Pani. I'd be suspicious of the cheapest R's, they will be cheap for a reason.
Go for a clean, well serviced, and not chavved-up 1199s. More power than you could ever need... Stick a 41 tooth rear sprocket on it and it pulls like a train. IMO the 1199s is the best-looking Pani by far - Best looking front end. Stick nice matt carbon rear hugger on to match the front and you've a stunner.
Having owned all 3, i would say, 899, bumfluff in a wish i had not started shaving kind of way. Best allrounder. 1199, 5 days stubble, ruff and rugged. Most vicious. 1299, clean shaven and slick. Sublimely quick. All good on fast a and b roads, all crap at town and gnarly roads, all excel on track with the 899 being the easiest to exploit.
Considering your options @wanzap1 i'd seriously consider the Pani V2. £14500 will get you a new bike that has everything you need.
Especially on a PCP deal.... Literally a few takeaways a month and you have a new bike in the garage.
That would be great if the OP didn't want a more modern proposition, based on your thinking I'd skip the 1098 completely and head to a 749R but none of these suggestions are remotely close to what the OP wants .....
For that budget you could get a 1299 base which would be my recommendation. A lot more refined than the 1199.
The 11 nor the 12 has that monster torque. I have a 12 and I find it a little underwhelming by comparison with my old 1198. The 1198 is a very capable bike.
if you want a package with minimum imput ( cash) then go with the 1199s, otherwise the 1199 base and then you have the option of some individual parts, suspension etc. I have the 1199s and 1299s and on the track I'm faster on the 1199 as the low down torque of the 1299 is a fight out of every corner.. but still jolly good fun
