I have just obtained a Bobcat XL kit and intend to power it with my Wren Supersport which is giving 19lbs of thrust.

We fly at 500 feet ASL and the normal temps are 50 - 70oF so we have cool dense air which gives optimum operating conditions. I suspect the Bobcat would fly very well on a 14lb thrust turbine in these conditions.I am currently operating a Boomerang Intro on a Wren 54 Mk3 (15lbs thrust) and a Jetco on a Ram500 (12lbs thrust ) and these models perform very well. Of course my idea of very well may not be somone elses, there are always pilots who want the biggest possible turbine in any airframe

While a P120 will compensate in the power department for any reduction in performance due to ambient temps and altitude remember it will be heavier and need a bigger fuel load which will decrease performance and make it a bit harder to fly due to increased wing loading especially in marginal conditions.

I think the Wren Supersport would be a good choice as it is very light and fuel efficient. Alternatively the latest Jetcat P80 gives around 20lbs thrust and is very well priced at the moment, hope this helps you, I am sure you will get some more good advice.
